Arriving at QVC’s runway show in New York Wednesday night, Camila Alves seemed to have a little extra sparkle, in the form of a stunning three-stone sparkler on her finger. The handbag designer was out for the first time since her Christmas engagement to longtime love Matthew McConaughey, and put her gorgeous engagement ring on display for all to see.

“I am really enjoying being engaged right now … no wedding plans as of yet,” she told reporters. But speaking to PEOPLE earlier in the week, she was happy to dish on her fiancé’s sense of style. “Matthew has great taste,” she said. “He always has great opinions on what works and what doesn’t.” He even gives input on Alves’s handbag line, Muxo, which she designs with her mother. “We are one big family so we share everything — including opinions on the creations for the line.”

Alves’s latest collection, which she’ll present on QVC this Saturday, was inspired by her recent travels through Texas, Arkansas, New Orleans, California and New York. “We are really having fun mixing all of the inspirations from the various landscapes that we’ve been collecting for some time now,” she shared.

The Brazilian beauty fell in love with fashion at an early age; her mother, a designer by trade, would let her help with various projects. “It taught me so much about design,” she explained. “And after I had moved to the States I was looking for something to do with my mom to help the family in Brazil … so we created our first handbag together.”

Though the pair has their moments — “Sometimes we butt heads like any mother and daughter,” Alves admitted — they feel “blessed” to work together. “We have a great relationship, and we create in a very unique way together.”

Catch Alves on QVC Saturday, selling the latest from Muxo (including her favorite, a leather satchel with a kiss-lock front pocket, right), plus sales from GF’s Geren Lockhart, Dennis Basso, Mark Zunino and Lori Goldstein (10 p.m. EST). And tune in Friday (10 p.m. EST) for launches from Cristina Ehrlich, Isaac Mizrahi, Fern Mallis, Karen Zambos, Marc Bouwer and Cynthia Vincent.

SHOP STAR LOOKS FOR LESS

Wednesday marked the beginning of New York Fashion Week, but last week, one of the city’s biggest fashionistas was already out and about. Speaking to PEOPLE Thursday at Godiva’s 2012 Valentine’s Day event at the Andaz 5th Avenue in New York, Blake Lively showed off a stunning Valentino ensemble, pairing the chic getup with — you guessed it — Christian Louboutin shoes.

The Gossip Girl star is known for her love of Louboutins — the designer even helps her decide which of his shoes to wear sometimes — but her latest interaction with him really takes their relationship to a new level. “My gosh, [the spring collection] was sent to my house today, and they’re so beautiful,” she revealed. “They’re amazing. I walked around my apartment wearing them.”

Her favorites? “These cage, crystal-encrusted shoes and one with a feather detail coming off of it.”

Lively, who doesn’t have a stylist, described her style muses as “women from times past: Katharine Hepburn, Audrey Hepburn, Grace Kelly. I love the sophistication. I love every single detail.” Sounds like she’d love to live among them, too. “I would love if I could wear little cut-off gloves every day,” she mused. “That would make me so happy. I’d go to a grocery store in a beautiful hat with lace dripping over the eye.”

But her handbag would certainly be current. “I do love my Chanel bags,” she said. “They come with me everywhere. That’s the truth.”

SHOP HOLLYWOOD’S HOTTEST SHOES — FOR UNDER $100

Back in December, Rachel Zoe was unusually tightlipped about expanding her fashion empire.

But now that she is unveiling a costume jewelry range ($195-$695, to be sold exclusively at Bergdorf Goodman and Neiman Marcus) and cold weather accessories, she can’t help but gush about the new endeavors.

“I’m a hand-talker, so that’s what this is about,” she tells WWD of an Art Deco-inspired collection of rings, cuffs and necklaces adorned with tassels and knotted accents.

The higher price point reflects a conscious expansion for Zoe, who previously found remarkable success in affordable fashion. “I’m someone who looks at my brand holistically,” she explains. “I go to style my show and I’m like, ‘I want hats. I want gloves. I want all these things. Okay, wait, I’m a designer now, so let’s do it,’” she says of the second category, which will offer cashmere-lined scarves, leather gloves and some faux, some real, fur pieces ($95-$1,500).

And though The Rachel Zoe Project has yet to be renewed for a fifth season, the stylist remains unflapped: “It’s been four seasons, it’s in 20 countries. Businessmen watch it, bankers, I get a lot of hits from a lot of different demos. So do I need it? I don’t know. After four years, maybe there’s something to be said for starting something new.”

GET READY FOR NYFW WITH THE BEST OF PARIS FASHION WEEK

As if it weren’t enough having a heel in her honor, Blake Lively also considers Christian Louboutin her personal shoe stylist.

“When I’m going to an event,” she says in the newest issue of ELLE, “I’ll send Christian a picture of my outfit and say, ‘What shoes do you think I should wear with this?’”

If we had to guess, the footwear guru then suggests a pair of his design from her “embarrassing” arsenal of red-soled masterpieces.

“I hope to have a few girls one day,” Lively continues. “If not girls, they better be trannies. Because I have some amazing shoes and bags and stories that need to be appreciated.”

Some girls have all the luck!

PLAY THE NUMBERS GAME IN ‘GUESS THE STAR BARGAIN’

Hats off to Kate: the Duchess of Cambridge was just named “Hat Person of the Year” by The Headwear Association. Beating Rachel Zoe, Ne-Yo, Justin Timberlake, Bruno Mars and Charlie Sheen — and taking a whopping 91 percent of the vote — the Duchess was the obvious favorite of online fans.

The Headwear Association — an organization founded in 1908 that “promotes hat wearing and the headwear industry throughout the world” — highlighted some of Kate’s best hats, including the velvet cabernet hat she wore on Christmas (left) and the memorable maple leaf headpiece by Sylvia Fletcher at Lock and Co. that she selected for Canada Day in July (center).

Kate is the third star to win top honors from The Headwear Association; Johnny Depp nabbed last year’s title, following in the footsteps (er, headprint?) of the organization’s first-ever winner, Brad Pitt. Tell us: Are you a fan of Kate’s hats?

They’ve lent their keen eye to designing jewelry, but Kate Bosworth and stylist pal Cher Coulter are teaming up for a new endeavor.

The New York Times reports that the duo is working on a “denim collaboration,” which makes perfect sense for the actress, who was named PEOPLE’s 2011 “Jean Queen.”

“Kate loves denim because it’s easy and casual,” Coulter told PEOPLE in October. “She always wears denim to remain comfy while running around town. On the flip side, she also loves to dress up denim by pairing it with a silky button-up and a necklace slung just under the shirt collar.”

We hope she infuses the forthcoming line with the same creative approach!

Leave it to celebrities to make an old trend new again. Headbands — once the preferred accessory of third-graders everywhere — made a triumphant return to the red carpet last night on actresses Michelle Williams, Charlize Theron and Busy Philipps.

Williams kept her blonde pixie under wraps in a vintage Fred Leighton for Forevermark headband, while Theron accentuated her soft do with a vintage Cartier band. Meanwhile, Cougartown‘s Busy Philipps put her own twist on the trend, using a simple platinum band to keep her updo in place.

We’re loving the return of headbands, but want to know what you think. Tell us: Are you a fan of the trend? Whose hairpiece was your favorite?

After making a splash in St. Barts with boyfriend Ryan Seacrest last week, it was back to business as usual for Julianne Hough on Tuesday as she made the rounds at two red carpet affairs.

The Footloose actress first stopped by Aéropostale and DoSomething.org’s fifth annual “Teens for Jeans” event at the Palihouse Holloway Hotel in West Hollywood, wearing a textured black top, circle skirt and matching pumps.

Later on, the starlet shimmered in a form-fitting nude dress with floral details by Rafael Cennamo at the Forevermark & InStyle Pre-Golden Globes Event at the Beverly Hills Hotel. Hough accentuated her outfit with a white-diamond ring and drop earrings from Forevermark, adding some sparkle to the carpet.

We think Hough — with her flawless skin and cute new haircut — is a hit in both of her looks, but we want to know what you think. Tell us: Which of Hough’s looks is your favorite?

WOULD YOU WEAR THESE TRENDS? VOTE NOW!

Ivanka Trump has been icing the wrists and ears of Hollywood stars with her namesake jewelry line for years now, but there’s one celebrity fan in particular that she’s extra proud to name drop these days.

Speaking to InStyle last week before accepting a Good Award from the Diamond Empowerment Fund, Trump discussed the “Oval Os” she was wearing — 18-karat white-gold earrings that feature 11.56 carats of diamonds. “I now call them my Oprah Os because she loves them,” the new mom revealed.

Winfrey may be one of few fans who can afford them; the large earrings go for $38,000, the medium (3.71 carats) for $13,000 and a small pair (1.23 carats) for $5,700. “O” my!

“I characterize my jewelry collection as timeless and glamorous but always classic,” Trump told PEOPLE in 2010. “I’ve added femininity and a modern twist to jewelry that resonates with both younger woman and an older consumer.” Tell us: What’s the most expensive piece of jewelry you’ve ever purchased?

WHO WILL BRING THE BLING TO THE GOLDEN GLOBES? VOTE NOW!

While details on the Duchess of Cambridge‘s 30th birthday celebration remain under wraps, royalty of another kind, reality princess and ShoeDazzle U.K.’s celeb stylist, Kim Kardashian, revealed her own commemoration of Monday’s occasion: a chic pair black pumps appropriately titled “The Duchess.”

The concealed platform design of the black pump channels the birthday girl’s signature style with “gorgeous, classic quilting and a really graceful silhouette,” Kardashian writes on her website and, for only £39.99 (or about $62) on ShoeDazzleUK.com, “would make any girl feel like a princess!”

Head over heels for Kate’s classic look just like the rest of us, Kardashian recommends the fancy footwear be paired with “lavish separates” or “an eye-catching dress” to make an impression on royal watchers. Check out the reality starlet’s warm welcome into the “30s club,” as she calls it, below.

YOU ASKED, WE FOUND: STAR LOOKS

She saves every penny on her hit CBS comedy, 2 Broke Girls, but blondie Beth Behrs recently made a splurge.

“I bought Christian Louboutins, which is what I’ve always wanted,” she tells LearnVest.com. But don’t judge too quickly: growing up in a working class family, Behrs learned to be a saver — and has continued to stay smart with her money, even as she’s risen to fame.

“I think I learned that kind of practicality from my mom and dad,” Behrs continues of her ability to budget. “There was a time in high school when girls were all getting designer jeans — Citizens and Sevens and all those — and of course my little sister and I were like, ‘Why can’t we have these jeans?’” she recalls. “It was definitely discussed that we couldn’t afford that, or we would need to figure out a way to afford that.”

So when contemplating her Louboutin purchase, Behrs gave it some thought before whipping out the credit card. “I have to justify it … I’ve never had nice, designer shoes,” she says. “But I got a classic, black suede boot. I could wear them every winter from now until I’m 84 and they’ll still be in style.”

Plus, they came at the recommendation of her costar, Kat Dennings. As Behrs recalls, “Kat was like, ‘Every girl should have just one pair.’” Tell us: What was your biggest fashion splurge?

From blushing bride-to-be to mega-watt model, Anne Hathaway is wearing many hats lately! The actress brings her best face to the TOD’s Signature Collection spring campaign, promoting a line of Italian bags and small leather goods that hit TOD’s boutiques in October.

Shot in London last year by photographers Mert Alas and Marcus Piggott (they did her fall campaign, too), the ads will bow in the weeks ahead, appearing in fashion magazines worldwide. “The campaign for TOD’s Signature reaches out to a new and younger clientele,” creative director Fabien Baron said in a release, adding that Hathaway was the right woman for the job. “We see a stunningly exquisite Anne as a classic beauty with a modern Italian edge — feminine and strong.”

Hathaway, for her part, is honored to be associated with the brand. “I have been a longtime fan of TOD’s and was very excited to be a part of exploring a new side of their identity with the launch of their Signature Collection,” she added. “The designs are classic and the materials are of the highest quality.”

Black Swan star Mila Kunis is spreading her wings, becoming the latest celebrity to join the Christian Dior family.

Charlize Theron also models for Dior beauty and J’adore Dior fragrance, and Jude Law, Sophie Marceau and Sharon Stone have ties to the brand, as well. Tell us: What do you think of Kunis’s first ads for Dior?

When Rachel Bilson dived into creating a collection for ShoeMint, she didn’t merely dip a toe.
