Answer/April 24th

We've got fresh fashion facts (and a few fresh faces too) in today's installment of What Was She Wearing: Answers! Read on to learn all the latest details from what Sienna Miller's sporting to Maria Sharapova's style secrets. Sienna Miller
Our readers (and all other clothing-obsessed individuals) closely track Sienna Miller's footsteps, because her natural fashion prowess turns outfit she wears into gold, figuratively speaking. Los Angeles is currently housing the ever-stylish guru for a few weeks while she finishes filming her upcoming movie, G.I. Joe. Miller was recently spotted at the Chateau Marmont looking glam in a pair of timeless Ray-BanWayfarer Sunglasses ($140) in Dark Tortoise and a Young, Fabulous & Broke Carrie Jumper ($280). She wore the outfit during the day, but, with the addition of a pair of great pumps, the jumper can easily be transitioned into a nighttime look. Miller was also wearing Yves Saint Laurent's Metallic Leather T-Strap Sandals ($540) but Report's Julia Sandals ($40) are a thrifty find and equally cute.

Kristen Bell
Although she is currently promoting like crazy for her movie, Forgetting Sarah Marshall, devoting time to her supporting role as Elle Bishops on Heroes, and offering intriguing narration as the voice of Gossip Girl, Kristen Bell still manages to find time to look enviably fashionable. We decided to induct the industrious actress into the site after receiving some inquries about the outfit she wore to TRL last week. The bright and colorful frock in question comes from Etro's Spring/Summer 2008 Collection and the Floral Print Chiffon Halter Dress ($2080) is in Etro boutiques now. We also found two other great floral print dresses that have that Etro look. Try Tibi's Coral Reef Dress ($420) or the Floral Sketch Jersey Dress by Development ($258) for less pricey versions. As for her outerwear, Bell opted for a Boys Cherokee Leather Jacket ($39.89) from Target, proving that wardrobe inspiration can come in places as unexpected as the kids' department. We must make note of her marvelous Jimmy Choos as well. The Lumiere Patent Leather Sandals ($585) originally debuted in the 2007 Cruise Collection, but due to high popularity, they were reinstated in the Spring/Summer 2008 line, and they are available in Jimmy Choo stores now.

Michelle Trachtenberg
The second newcomer in today's What Was She Wearing, Michelle Trachtenberg, earned her place in our readers' hearts when she visited MTV last week in some appealing wardrobe pieces. She glistened in Foley + Corrina's Rhinestone Collar Top ($429), which is currently available at the company's LA store (323.944.0169). If you'd prefer a dress version of the top, you're in luck, just call the LA store and ask them to send you the Rhinestone Collar Dress ($495). Trachtenberg also selected a pair of J Brand jeans, specifically the 10" Ankle Skinny Stretch Jean in black ($159), and finished her outfit off the Marc Jacobs way in a pair of Jacobs's Leather Misplaced Heels ($545), available in Marc Jacobs boutiques now. A peep-toe version of this shoe is currently for sale on eLuxury.

Maria Sharapova
As the majority of the ladies we feature on our site are actresses or models, it excites us to branch out when given the opportunity with someone like Maria Sharapova. We received a handful of questions after Sharapova appeared on The Late Show with David Letterman on Monday, and discovered that we too adored the ensemble the tennis star wore. It pleases us to inform you all that both her crème top ($298) and black skirt ($294) are BCBG Max Azria, and they will be available in stores on July 30th.
