Ashlee Simpson-Wentz has never looked sexier, and at the Paris in L.A. party in honor of lingerie designer Carol Malony, the new mom showed off her enviable body-after-baby figure in — what else? — lingerie. “There is nothing like a great set of lingerie,” Ashlee said, showing off a bra by the designer, paired with high-waisted Catherine Malandrino shorts, a tuxedo blazer and Jimmy Choo platforms. “Carol is really detailed and intricate. I love that about her lingerie.” Ashlee told PEOPLE. Among her favorite pieces? The “Fairy Tulle” bra set that she just so happened to be wearing to the West Hollywood party. “The underwear that go with it are amazing as well — [but] only my husband can see. It’s nice for me, mostly, to feel comfortable and sexy,” she continued. And that, Carol Malony says is the philosophy behind her designs. “It’s all about making you feel terrific.” – reporting by Scott Huver

Looking for jeans with a $200 fit without the price tag?  Look no further than Gap’s latest denim line — the 1969 Premium Jeans Collection.  From Halle Berry and Molly Sims to Ashlee Simpson and Emma Roberts, fashion forward celebs jammed to tunes spun by Joel Madden Thursday night, while perusing the new wallet-friendly collection at the 1969 Jeans Shop, a temporary pop-up shop on trendy Robertson Blvd in West Hollywood.  And the ladies couldn’t stop raving about the line, which features 14 different styles for men and women in the softest denim and most stylish washes, all for under $60.  “Gap is always good at the classic jeans — they fit [well] and they’re easy to wear,” Simpson told PEOPLE.  And she wasn’t the only enthusiast. The favorite pick of the evening?  The “Always Skinny” jean, rocked by Berry, Cobb, Roberts, and Entourage’s Constance Zimmer.  “I just picked up four, five new pairs,” confessed Roberts.  Gap creative director Patrick Robinson is to thank for the new recessionista obsession: Robinson spent a year and a half fine-tuning the line, from shopping around for fabrics, and teaching factories how to make those perfect hand-made finishes, to working with several body types to master that perfect fit.  “For me, honestly, these are the best fitting jeans in the world.  We’ll go up against any brand of any jean, and these fit better,” says Robinson.  “We want[ed] jeans that, for women, make you have the best butt in the world. You want to be able to wear these on a date, you want to be able to wear them out on those nice steak dinners.” And we will – It’s hard to say no to booty- and wallet-friendly jeans!  The Gap 1969 Jeans Collection is available in Gap stores and online at gap.com starting August 13. – By Shruti Dhalwala

Ever since she played Daisy Duke in Dukes of Hazzard, Jessica Simpson has made the character’s iconic cutoff shorts one of her own style signatures — pairing them with everything from floaty floral blouses to sexy bustiers for her stage costumes. But looks like her little sister Ashlee has the same idea, taking her adorable baby son Bronx out in her own faded cutoff shorts. We can’t help but compare the two — and be totally wowed by their shared genes for fabulous legs! We want to know what you think, though. Vote in our poll below, and tell us: Which Simpson sister wears her cutoff shorts better?

Just over a month after the birth of baby Bronx Mowgli, new mom Ashlee Simpson-Wentz is back to her famous blonde hair.

Tell us: What do you think of Ashlee’s blonde do?

Stylish singer and dad-to-be Pete Wentz wants you to know that it’s not easy looking as good as he always does. Pete opened up to PEOPLE about his hair challenges last night in Chicago, where he hosted Gen Art’s 6th Annual Fresh Faces in Fashion and sat front-row during the Windy City’s fashion week with wife Ashlee Simpson-Wentz by his side. “Here’s the thing about hair; I think most people think that I have Lego hair, like I can just take it on and off in one piece, and that’s not quite the case — although pretty close,” he said. “I refer to this [phenomenon] as Lego hair, when people think that about me.” Pete went on to joke about the importance of spending enough time making your hair look good. “I think hair is just, like, the most important thing about you,” he joked. “Besides your soul, or maybe your heart, or maybe your crotch…. Or maybe the order I just put those in says a little something about who I am,” he laughed before heading off with friends to end the night at his bar Angels & Kings.

Ashlee Simpson has cycled through plenty of looks in her career, but she seems to be sticking with her long red hair for now. But our question for the mom-to-be is, can you see from under those bangs? Sure, they match husband Pete Wentz’s carefully straightened fringe, but we’d start bumping into things if we had such long bangs. We want to know what you think! Tell us: Would you wear your bangs as long as Ashlee?

His Clandestine Industries line has a collection that recently hit Nordstrom, and Pete Wentz says one major inspiration is his new — and pregnant! — fiancee, Ashlee Simpson.”She is a good sounding board for me,” Wentz told PEOPLE on Thursday. “She’s really supportive and always positive but sometimes she’ll get me to rethink [things]. Like I’ll be like, ‘We should do a half-plaid, half-pastel hoodie!’ And she’ll be like, ‘I like it, but maybe you should do it as two separate hoodies.’ She’s good like that.” As for Ashlee’s new line at Wet Seal, Pete admits, “I haven’t really seen it [yet].” When asked what life is like not only as a fashion designer and musician, but also as a husband and father to be, Wentz sums up his feelings very simply: “I’m happy!”

Looks like Jessica isn’t the only Simpson sister with a design line. Wet Seal just announced that Ashlee Simpson will be launching a collection of T-shirts for them. According to Wet Seal, Ashlee’s collection features designs inspired by her own personality, sense of style and album artwork. “I was inspired by so many fun, wonderful things as I was recording Bittersweet World and it’s been great to carry through those inspirations into these new shirt designs,” says Ashlee. “I hope my fans love this album and rock out in these shirts!” Ashlee’s line will launch nationwide on April 22 — the same day her new album, Bittersweet World drops. Tell us: Will you buy Ashlee’s T-shirts?

Shedding their school girl image, knee-high hosiery is getting a fresh update from some of Hollywood’s most stylish starlets. Ashlee Simpson keeps it sporty, pairing them with her low-top Converse sneakers. Jessica Alba playfully wears them in a contrasting color over a pair of black opaque tights. And Rihanna keeps it sexy in thigh-high pair that show just a hint of skin. We’re not completely sold on this trend, but we’d love to hear from you. Tell us: Would you wear this look?

Looks like the new year is bringing some drastic changes for lots of our favorite stars — at least when it comes to their hair. In the past couple weeks alone we’ve seen Amy Winehouse go platinum, Jessica Biel go honey blonde and Lindsay Lohan fade to black. Now we can add Ashlee Simpson to that growing list. The singer showed off a new dark auburn hue while stepping out with boyfriend Pete Wentz for the Cloverfield premiere in L.A. last night. And while changing up her look is nothing new to the star, who as a teen sported signature dark locks, we’d gotten so used to the softer blonde look she’d favored recently. But we want to know what you think. Tell us: Should Ashlee stick with this auburn look, or should she go back to blond?

Ashlee Simpson turned up at the Hollywood Style Awards last weekend with such pin-straight hair that we had to look twice — and compare it to her usual soft waves!

We can’t decide which look we like better for the pop singer, so we want to know what you think. Tell us: What’s Ashlee’s best look? Wavy or straight?

When we spotted Ashlee Simpson sitting front row at the BCBG Max Azria show last week, we had no idea that she was there with a purpose — getting a hot dress for the VMAs red carpet. But as soon as look 30 rolled down the runway, Ashlee turned to her mother Tina and excitedly pointed it out as a favorite, according to those seated near her. And she turned up only four days later in the chic black dress on the VMAs red carpet! As stylish as the dress looked on the runway, we think Ashlee did it justice with her own sexy style. Tell us: Do you like Ashlee’s VMAs dress? Do you like better on her or on the runway?

Both Ashlee Simpson and Jessica Simpson were in N.Y.C last night, hitting some of the many Fashion Week parties. Jessica actually turned up to support Tim Gunn at the launch party for his new show, while Ashlee cozied up with boyfriend Pete Wentz at the Fashion Rocks event. While sisters may not have been in the same room, they had the same hot makeup — check out their smoky eyes! We love their barely-done faces that enhance the wow factor of their dark-shaded lids. And it’s nice to see a makeup look that works equally well on brown eyes like Jessica’s and blue eyes like Ashlee’s. Try out the look for yourself with Stila’s Smoky Eye Palette. Tell us: Who wears the look better? Jessica or Ashlee?

What’s it like to sit directly behind Ashlee Simpson at a fashion show? Blinding! As the singer settled into her front row seat at this morning’s BCBG Max Azria show with her mom Tina next to her, photographers mobbed the petite blonde, who sat posing in her slim black dress and oversize hoops. Brittany Snow, clad in a backless BCBG dress, leaned over to enthusiastically greet Ashlee, saying “It’s been so long!” On the other side of Brittany, Sophia Bush happily chatted away with the throngs of reporters around her. Ciara slipped into her seat at the last minute, her rakish beret staying perfectly in place. Once the chaos cleared and the show began, a procession of pretty pale chiffon and silk dresses filled the runway. The designer described the Spring ‘08 collection as “using layers of transparencies” with “shadows of blush foundation and lipstick pink.” Think this means Ashlee is contemplating shedding her signature black?

From the red carpet to the beach, Hollywood starlets can’t get enough of their straw fedoras. We first spotted Ashlee Simpson a few months back sporting a purple Cha Chas style — and she’s still wearing them, topping off her all-black esemble with a banded Cha Chas this week while celebrating her Seventeen cover. Carmen Electra finshed off her rocker t-shirt and Vix bikini bottoms with a vintage straw hat from New Orleans while lounging at the Polariod House. Rumer Willis brought the trend to the Superdad premiere after-party, pairing her vintage hat (actually from dad Bruce Willis’ collection!) with a white party dress. Get a fedora now to finish out the summer and wear it through the fall! We found you some celeb-fave hats — and more affordable options.

We spotted Ashlee Simpson in sheer knee-highs paired with Converse sneakers last week, but we didn’t realize it was the beginning of a signature look for her! While in New York yesterday, the singer stepped out in two different pairs of stockings — knee-high with sneakers again while accompanying boyfriend Pete Wentz to a TRL taping, and then a pair of racy thigh-highs with her little black dress to Wentz’s birthday party at night. What do you think of Ashlee’s new look: Would you wear knee-highs and thigh-thighs like Ashlee? Do you like them on her?
