Though we always have our eyes peeled for the latest celebrity and runway trends, one of our favorite off-the-clock activities is to check out what the most popular trending topics are currently in the Twitterverse (if you don't already, be sure to follow us @whowhatwear!). In the spirit of these hilarious hash tags such as #itsreallyannoying or #getoverit, we think there is one that aptly applies to today's What Was She Wearing: Answers! feature. You see, this bi-monthly installment goes beyond just helping you track down the exact pieces that your favorite fashionable femmes are sporting. It also gives you all of the information on similar styles, because #letsbehonest, when it comes to chic clothing options, the more the merrier! So read on for all the dressing details, let us know what your favorite looks are, and keep those questions coming!

Sarah Jessica Parker
Sarah Jessica Parker certainly knows how to carry off a fancy frock, whether it's Chanel Haute Couture on the Academy Awards red carpet or an anything-but-mellow yellow Lanvin dress at the Warner Bros. ShoWest Presentation at the Paris Hotel in Las Vegas. Speaking of the latter, Parker made you swoon when she wore the Alber Elbaz-designed Silk Twill Dress ($7818, 310.550.5900) from the French fashion house's S/S 10 collection. Happily for those of us who can't afford said Lanvin confection, there are loads of similarly shaped one-shoulder selections available that can help you get the look. Just try Thread Social's Asymmetric Dress ($495), Diane Von Furstenberg's Carmona One-Shoulder Dress ($550), or Milly's Asymmetrical Ruffle Dress ($350). Additionally, if you are in love with the hue of Parker's pick try Nicole Miller's Elle Dress ($330) as well! The Sex in the City star finished off her ensemble with pale pink heels from cult-label Charlotte Olympia, but make sure to try bebe's Jasmin Leather Bow Pumps ($120) or Guess' Carrie Pump ($90) to make a perfect Parker-esque statement at your next cocktail affair!

Kate Bosworth
Kate Bosworth has certainly emerged as a serious style star with an ability to look both directional and darling. Seen here at a lunch date with friends in West Hollywood this week, Bosworth proved she has a serious beige crush in Chloe's Crepe de Chine Tank ($470) and Calvin Klein Collection's Basket Weave Pencil Skirt ($350, 212.292.90000)Â--try Halogen's Pencil Skirt ($68) for a smart skirt alternate. All you need after that is a chic neutral bag; Bosworth opted for Jil Sander's Sand Tubular Handle Leather Bag ($1195, 212.925.2345) but Brahmin La Scala's Adora Satchel ($325) or J. Crew's Marquee Satchel ($278) is also stylish and simple.

Sienna Miller
Seen running errands in New York City earlier this month, Sienna Miller sported a seriously stylish yet low-key outfit. You, dear readers, were curious about her brilliant basics, such as the 7 For All Mankind Gwenevere Gummy Jeans ($169) and Twenty8Twelve Matt Shirt ($187) she wore layered over a vintage cotton jumper; try BDG's Ankle Cigarette Jeans ($54) and Gap's Chambray Shirt ($60) for some lower-priced pieces. But of course it was Miller's killer accessories that really stole the show. The actress selected Louis Vuitton's Monogram Antheia GM Bag ($2970, 310.859.0457), and Nicholas Kirkwood's Metallic Oxfords ($795)Â--two chic choices, certainlyÂ--but you can easily get the vibe of these key pieces without breaking the bank. Just make sure you try Rag & Bone's Patent Oxfords ($325) or Luxury Rebel's Birken Oxford Jazz Shoes ($185), Contributor by Rachel Comey's Satchel or Topshop's Tap Lock Slouch Bag ($80), and the classic Metal-Frame Aviator Sunglasses ($135) from Ray-Ban to get Miller-ific in no time flat!

Lauren Conrad
Reader-favorite Lauren Conrad never fails to whip our readers into a fashionable frenzy, and it is our pleasure to calm everyone down with outfit details galore! Seen at the Spring Trends Dinner at Los Angeles' famed Chateau Marmont last week, the Sweet Little Lies author looked amazing in 3.1 Phillip Lim's Belted Bib Dress ($675, 310.358.1988) in Wheat. Though we think her exact selection is certainly worth checking out, we can also recommend 3.1 Phillip Lim's Rolled Sleeved Gathered Dress ($495) or Anne Taylor Loft's Cotton and Linen Dress with Ribbon Waist Tie ($80) for those of you who want look-a-like options. Conrad rounded out her ensemble with Christian Louboutin's Quepi Reci Platform Sandals ($895) and her beloved Marc Jacobs bag. Though her exact carryall is no longer available, be sure to consider Rebecca Minkoff's Basket Weave Morning After Bag ($635) with Melinda Maria's Pyramid Bangle ($94), Low Luv x Erin Wasson Crater Bangle ($55) or House of Harlow 1960's Gold Thick Stacking Bangle ($52) for some Conrad-approved accoutrement!Â--KM
