Hopefully you're enjoying the final two weeks of 2010 and are doing something seasonally appropriate, like baking yummy cookies or hanging out with your favorite friends. But whatever activity is occupying your time this holiday season, we know you want to be well-dressed while doing it, and fortunately today's installment of What Was She Wearing: Answers! can help you achieve that! Just take note of our fabulous quintet of stylephiles--including Rashida Jones, Kate Bosworth, and more--and we'll show you how to make their laudable outfit selections into noteworthy ensembles of your own!

1. Kate Bosworth
While you are definitely fans of Kate Bosworth's glamorous red carpet attire, you're just as easily won over by her perfectly assembled daytime outfits. The latest look you liked was a casual combo Bosworth showed off while out and about in Los Angeles earlier this month. The actress was snapped wearing a rust red H&M jacket over a delicate white Chloe tank (from the S/S 09 collection) and Topshop's Vintage Jeggings ($70). To finish her casual look, Bosworth selected Alexander Wang's Rocco Mini Duffle ($875) and Celine sunglasses: both are obsession-worthy accessories to say the least! To emulate Bosworth's on-point outfit, start with Kenny's Lacey Lace Tank ($80) and layer it with a lightweight jacket or cardigan (Topshop's Rust Knitted Open Cardigan ($80) and American Apparel's Solid Rib Oversized Pocket Cardigan ($42) are two of our favorites). Next, grab a pair of her exact skinny jeans and then finalize your look with Ray-Ban's Caribbean Sunglasses ($139) and Topshop's Four Pocket Holdall Bag ($90). And voila! You're the spitting image of the fashion frontrunner.

2. Rashida Jones
Pairing a casual jacket with chic trousers makes for an exceptional outfit, as Rashida Jones showed us at the Devon clothing line launch in Beverly Hills two weeks ago. The actress wore a printed shirt from said designer with cropped 3.1 Phillip Lim pants and Lanvin for H&M heels (a covetable pair that sold out quickly). But it was Jones' casual outerwear choice--an Isabel Marant jean jacket--that really piqued your interest. If you'd like to make a similar statement this season, pick up All Saints' Lamara Rider Jacket ($80) and be sure to give it that Jones panache with a pair of Talbots' Signature Fit Cuffed Ankle Pants ($129) and Forever 21's Suedette Bow Pumps ($23). The results will be just as memorable, we promise!

3. Rihanna
Rihanna never fails to excite the world at large with her radical sensibilities, whether that means a drastic hair color change or simply by incorporating a quirky piece or two into her ensembles. Speaking of the latter, you spotted the singer en route to the X Factor in London early this month and liked the way she accessorized two Alexander Wang pieces--a sweater dress (from a previous collection) and the Chunky Scarf ($375)--with an unexpected headwear choice: a Bape camouflage hat. To replicate Rihanna's on-the-go ensemble, we'd start with Marc By Marc Jacobs' Patti Sweater Dress ($248). Not only is it a spot-on alternative, but it's also a great piece to have on hand this winter. To add an extra layer of warmth, bundle up with either Rag & Bone's Pocketed Chunk Knit Scarf ($115) or Aubin & Wills' Raeburn Merino Scarf ($115). Last, but certainly not least, follow in Rihanna's footsteps by throwing on Windsor's Camo Cabby Hat ($13) for that final finishing touch.

4. Elle Macpherson
You, dear readers, certainly appreciate an oh-so cozy ensemble, which is why we were not surprised to see the plethora of inquiries regarding Elle Macpherson's latest sartorial endeavor. The Australian model/designer/mother braved the chilly UK weather on a school run in London late last month by bundling up in Isabel Marant's Michal Shearling Suede Jacket ($3220, 212.219.2284) over a cream Banjo & Matilda Surfer Cable Knit Sweater ($699). Sure, it may be difficult to find a similar white leather jacket, but if you're still on the hunt for a great shearling style, look no further than Forever 21's Worn Leatherette Motorcycle Jacket ($43) or Nasty Gal's Shearling Aviator Jacket ($98); both are obsession-worthy iterations for a fraction of the cost! As for the bottom half of her outfit, Macpherson selected a pair of MET leather pants and Belstaff boots, resulting in a very stylish biker-like mix. Just pick up Rich & Skinny's Legacy Zip Leggings ($185) and Aldo's Chalita Platform Pull On Boots ($157) to find yourself in a look-a-like, Macpherson-approved combo.

5. Kristen Bell
Spotted: the voice of Gossip Girl experimenting with high-impact color for her after-hours look. Earlier this month, Kristen Bell was snapped arriving at Claridge's wearing lots of Salvatore Ferragamo--Cream Line Trousers ($580, 800.628.8916) and an Orange Silk Blouse ($1990, 800.628.8916) from Resort 11, to be exact--and the Brown Suede Saddle Bag ($1390, 800.628.8916) from the label's F/W 10 collection. While we adore Bell's designer picks, we've found some amazing alternatives to help you achieve a similar look without breaking the bank. We love the vibrant hue of Bell's top, and think Joie's Denisa Blouse ($214) is a top-notch match worth checking out. Just be sure to style it with a crisp pair of white trousers, like Elie Tahari's Talia Pants ($248), and Kimichi Blue's Suede Buckle Bag ($68) for an outfit that mimics Bell's chic styling perfectly.--Jessica Baker
