What Was She Wearing: Answers!

. Your WhoWhatWear.com editors are an excited bunch right now, an unsurprising fact considering that this is the season for backyard barbecues, upcoming summer vacations, and of course, the recent resort collections! And even though we have been obsessing over the latest creations from our always-fashionable favorites—including DVF, ODLR, and YSL—we haven't lost sight of the important task at hand: your sartorial inquiries. Whether it is Rachel Bilson's darling romper or Kate Beckinsale's knit cardigan, you love the way chic celebs are opting for a neutral palette and want details about their un-bright outfits. We've gathered all that need-to-know information for today's edition of What Was She Wearing: Answers!, so get ready for some fabulous fashion facts and spot-on style suggestions! Rachel Bilson It's obvious that Rachel Bilson is a summer favorite of our dear readers, and we can definitely see why! She never fails to impress with her cool, California style, so when we spotted her in an adorable 3.1 Phillip Lim Lace Romper ($425) en route to the Burberry Store in Beverly Hills, we knew it was only a matter of time before your inquiries would start to pour in. If you're on the hunt for a similar one-piece to add to your warm-weather wardrobe, A.Y. Not Dead's Laser Cut Jersey Playsuit ($136) will surely fit the bill. Bilson brightened up her lacey look with a pair of Rag & Bone Victoria Wedges ($385) in Nude, which are worth every penny! (Don't miss Report Signature's Mazeau Wedge Sandals ($195) for an equally enviable, budget-friendly version.) For a few finishing touches like Bilson's Chanel bag and Ray-Ban Wayfarer Sunglasses ($195) in Tortoise, we particularly like BCBGeneration's Zoey Satchel ($118) and ASOS' Tortoise Retro Sunglasses ($17); their comparable qualities will give you a foolproof Bilson look. Rachel Zoe Whether she's sitting front row at Fashion Week, styling your favorite actresses' red-carpet ensembles, or starring in her delightful Bravo show, Rachel Zoe's personal fashion choices are always on-point. Most recently, you were captivated by the lovely number she wore to the opening of the Andy Warhol Black and White exhibit at PRISM Gallery in early June. Zoe accented her 3.1 Phillip Lim Jumpsuit (from the F/W 08 collection) with obsession-worthy pieces like a Brian Atwood clutch, vintage hat, and Louis Vuitton wedges (also from F/W 08). Sadly, none of her exact pieces are available, but don't fret because we have selected superb in-stock alternatives for your shopping pleasure. To reiterate Zoe's look, make sure to get your hands on Yellow is Gold by Sunshine and Shadow's Silk Jumper ($50), Free People's Daisy Hat ($29), and Cole Haan's Air Lainey Platform Wedges ($138). Alessandra Ambrosio Brazilian model Alessandra Ambrosio lights up the pages of Victoria's Secret catalogs and runway shows with her stunning body and beautiful features, but it's her off-duty appearances you are most interested in. The sexy catwalker and mother—we are completely jealous of that post-baby body—stepped out in New York City for some lunch and shopping wearing an A.L.C. Striped Boatneck Shirt with Snap Detail ($124) tucked into Sass and Bide's Heart of Glass Hulsey Parks Shorts ($160), which are unfortunately out of stock at this time. The striped shirt is a must-have closet staple, so we recommend you look into Armor Lux's Cotton Striped Tee ($54) for a similar style. If you are still searching for that great pair of denim shorts to get you through the summer months, Calvin Klein's Boyfriend Roll-Up Jean Shorts ($40) will look great with a casual tank or dressed up with a sweet blouse. Ambrosio layered her top half with a Topshop Draped Tencil Biker Jacket ($145) and the Louis Vuitton Monogram Denim Duffle GM ($3,360, 866.VUITTON). ASOS' Leather Slot Through Satchel ($110) is just as functional, but without the heavy price commitment. Another great piece to have in your wardrobe is a simple, neutral flat like Ambrosio's Sue London The London Slippers ($168) in Horace. This shoe style can be paired with just about any outfit, so start your collection with either the model's exact pair or try Aldo's Bessora Flats ($70) today. Kate Beckinsale There is no doubt that actress Kate Beckinsale is a true British beauty (we have always yearned for those luscious brunette locks!), and it is clear you were experiencing some envy of your own when she combined two of last month's trend reports: crochet and clogs. Beckinsale looked cute and casual for an afternoon stroll in Santa Monica earlier this month wearing Line's Crochet Loop Cardigan ($220) and black Chanel Clogs ($895, 800.550.0005). You too can capture the spirit of this charming combo with Spiegel'sCrochet Shrug ($39) and N.Y.L.A.'s Rhedyn Clogs ($100), which will have you stepping out in style all summer long. A few subtle finishes—Hard Tail's Linen Drawstring Cargo Shorts ($83, 310.393.8787), Natalie Gonzalez's Liquid Glazed Croc Hobo ($3,250), and Dior's 61 Open-Temple Sunglasses ($295) to be exact—completed her must-have daytime look. However, we think BCBGeneration's Lulu Hobo ($138) and Dita's Supa Dupa Sunglasses ($158) are worthy substitutes for those pricier accessories.—Jessica Baker Photos of Rachel Bilson and Kate Beckinsale, courtesy of Splash; Photo of Alessandra Ambrosio, courtesy of INF Jump to read the next story .
