With her uncanny ability to add some casual cool to even the most classic silhouettes, Rachel Bilson once again lends her expert eye as a guest editor for Piperlime.

The Hart of Dixie star, who also shills for Sunglass Hut, curates a new selection of affordable to aspirational items to reflect her trademark “comfy” style. “I like to say I’m a moody dresser,” she explains. “I wake up and then I kind of dress according to how I’m feeling.”

Her picks include sensible Rachel Comey booties, a pleated Vince maxi skirt (reminiscent of this bohemian look by Rachel Bruno) and a Splendid striped henley, now on sale for $55. “I love stripes and I love cozy,” she declares. ‘Nuff said!

SHOP MORE STAR-APPROVED ITEMS IN ‘I REALLY LOVE MY…’

Ovarian cancer is one of the world’s least-recognizable cancers, so why not choose two of the world’s most recognized stars to draw attention to the cause? Kim Kardashian and Kelly Ripa are teaming up for the second year in a row to publicize QVC Presents Super Saturday, a shopping event broadcast live from the Hamptons and featuring designer deals at up to 50 percent off. Proceeds from the sale, airing Saturday, July 30 at 2 p.m. ET, will benefit the Ovarian Cancer Research Fund, a cause close to both women’s hearts. “With so many women affected by ovarian cancer each year, the importance for awareness is now more important than ever,” Kardashian said in a statement. “It’s truly a pleasure to work with Kelly to make sure that every woman knows the facts about this unrecognizable disease.” Super Saturday‘s broad reach — it used to be a sale just for celebrities — will raise awareness about the disease, and give shoppers access to great gets from Laura Geller, L’Oréal Paris, philosophy, Judith Ripka, Honora and more. “I am thrilled to be teaming up with Kim again to support such a wonderful cause,” Ripa added. “We always have a blast when we’re together and it’s great to be able to help spread the word about such an amazing event.” –Caroline Slutsky

SHOP OUR EXCLUSIVE DEALS

Her Gossip Girl character Blair Waldorf is often spotted in pricey designer dresses — hello, Jenny Packham — but Leighton Meester says she prefers to save a few bucks when she shops. “The last time I popped out my credit card I bought [a] Proenza Schouler dress,” she tells PEOPLE, adding that she picked up a few others that same day during a sample sale for the brand. “I love sample sales! Proenza always has the good ones, and is one of my favorite designers. Most of the Proenzas in my closet are from sample sales.” Not one to splurge too much, she’s also a do-it-yourself type, currently redecorating her own home. “I’m buying tons of magazines, too, like Elle Decor, and I’m addicted to them now,” she admits. “Even though one day I will be done decorating, I’m still going to be buying them because I love looking at them.” Tell us: Are you a sample sale shopper? –Reporting by Paul Chi

We hardly recoginzed you, Gwen! For a recent play date in L.A with her son Kingston, the singer swapped her typical bright hues and bold patterns for a cozy and subdued grey sweater dress. And while the color is much more somber than we usually see on the always-stylish singer, the loose look is something we’re sure to see in the coming months — since she’s expecting her second child! And whether you’re pregnant or not, you can still get your hands on Gwen’s comfy BCBG (non-maternity) sweater dress — on sale now $189 from $378 — at bcbg.com. For a similar look for less, try this Lewis Cho tent sweater dress, on sale for $79 from $265, shopbop.com.

The mom-to-be is taking cues from other stylish pregnant stars and steering clear of maternity clothes. Jessica Alba stopped by TRL wearing this adorable off-the shoulder Gold Hawk dress with a chic jeweled top.

Though we can’t wait to catch a glimpse of Jessica’s baby bump, we love the fact we can still get her look- – and on sale! Get Jessica’s Gold Hawk dress (in black), on sale $119 from $298, at saks.com. If you like the style you can also show some shoulder in this Bardot Neck top, $41, asos.com

Singer Lily Allen arrived at early this morning on a horse-drawn carriage to be greeted by the Harrod’s owner Mohamed Al Fayed and opened the famous sale in cheeky mode telling the eager crowds: “I have had a preview and there is not much left!” Dressed in a black sequined sleeveless dress by Jasmine di Milo and silver high heels, Allen toured the store, while giggling like a kid in a candy store. Some stops included the fine jewelry department where she posed wearing a diamond watch by Chopard and a necklace by Cartier. On what she will be wearing in 2008 she exclaimed: “Maternity clothes!” She also confessed that she hadn’t found out yet what hip and stylish moms-to-be wear, but she has declined offers to design her own maternity line. “I am not the right person. My demographic is young girls and I don’t think it would be suitable.” Allen also proved to be a girls’ girl, honing in on “jewelry and handbags and shoes.” Any tips for finding a bargain? She told PEOPLE “I am not good at finding bargains. I am good at finding expensive ones.” One thing she is avoiding is cigarettes — the newly pregnant singer declared that she “has given up smoking.”
