Lindsay Vallan

Michelle Trachtenberg was all smiles working a mint Rails Clothing blouse, Black Orchid skinny jeans ($128), and Rachel Zoe slingback wedges ($249, originally $355) while leaving a party in Brentwood. The actress glammed up her solid separates with this snake chain-strap Vince Camuto bag ($198), double-wrap Lindsay Vallan necklace, and oversized sunglasses. Re-create Michelle's sweet Summer look with some of her exact pieces, then later pair them with this black sheath by The Limited ($90) to turn heads at cocktail hour.

Jessica Alba stepped out in Santa Monica, CA, fusing prints, pastels, and neons to perfection, then she balanced her colorful look with a white Gerard Darel crossbody bag — here it is in grey and tan ($315). The actress donned a grey polka-dot blouse by Splendid with cuffed boyfriend jeans and hot pink and yellow neon wedges, then layered on a striped green blazer for extra pizzazz. She finished off her bold style with Lindsay Vallan wrap necklaces, double-finger ring, and orange shades. Re-create Jessica's trendsetting look with a light blazer, polka-dot blouse, boyfriend jeans, and neon wedges for your next daytime adventure.

Jessica Alba was spotted heading into her Santa Monica office in a playful and polished ensemble — purple skinny jeans, an Aztec-print tank, and tie-dye Tory Burch shades — while toting all her work essentials in a leather Tory Burch briefcase. She layered a black blazer over her eye-catching outfit, then completed it with studded flats, a dual-chain Lindsay Vallan necklace, and diamond stud earrings. Style similar purple skinnies with a tribal tank and pointed flats like Jessica, or pair your grape denim with a white tank and tribal sandals; then don't forget standout shades like Jessica's pair to complete your punchy Spring ensemble.
