Spotted leaving the Tabernacle Pub in London, Lily Allen proves that she knows how to incorporate bold colors into her wardrobe in a fresh way. The pop star picked Acne's Smith Biker Jacket ($949) in an excellent shade of emerald suede (it's also available in black and crimson). The loose fit makes it the ideal piece to throw over a floral frock or wear with your beloved boyfriend jeans, like Allen's Generic Girl Ripped Jeans ($375), also from Acne. To get a similarly boxy and bright outerwear option try Silence & Noise's Satellite Moto Jacket ($128) or their Fleece Motorcycle Jacket ($58) with ASOS's Roll Up Boyfriend Jeans ($50) in Mid-Blue. The it-Brit opted to accessorize her look with trainers, as they say, but you could definitely dress this ensemble up with a pair of wooden wedges or black heels for a fancier end result. Just grab a great clutch-Allen reached for Prada's Royal Calf Rosette Clutch ($1060, 212.826.8900) but we like High Fashion's Pleated Clutch ($198) just as much-and you're all set for a casual night out!
As an actress who plays a rebellious and fashionable teenager in Gossip Girl and a real-life aspiring rocker, it is no wonder that Taylor Momsen's current look is as cutting-edge as it is chic. While attending a CW network press event, Momsen wore Rag & Bone's Silk Tank($203) with Elise Overland's liquid leggings (her exact pair are no longer available, try the Liquid Leggings ($86) from Member's Only for body-con bottoms that resemble Momsen's pick). The zipper-embellishments on her blouse de-sweeten the potentially prissy print, while her Mikhael Kale Cropped Leather Jacket ($1065, 646.619.6857) also adds a tough element to her masculine-feminine mix. As an additional alternative, check out the Dallin Chase Jasper Leather Jacket ($598): it's a slightly more affordable, yet equally rough-and-tumble option!
Though Rihanna has been making serious sartorial waves with her red-carpet ensembles, we are equally smitten with her off-duty looks. While en route to meet with fellow musician Kanye West, the directional dresser wore Stella McCartney's Backless Cardigan ($693, 212.255.1556) with a pair of Chloe's killer nude Over-the-Knee Boots ($1195). Thigh-high flat footwear is a trend that will carry on through summer and well into autumn, so we suggest investing in the songbird's high-end selection or Joie's Over-the-Knee Leather Boots ($525). Wear them with a strappy summer dress or your favorite jean shorts and lightweight sweater, like BDG's Sailor Stripe Cardigan ($48). Finally, Rihanna added some posh polish with Erva's Razza Bag ($1170, 212.826.8900), which is a particularly stylish way to stow all of your daily essentials (American Apparel's Watery Faux Leather Oversized Tote ($65) in Smoke would also do the trick!)
While out and about with friends in New York's Tribeca neighborhood, Olivia Palermo managed to create the perfect high-low mix with her clothing choices. While most of her outfit is composed of simple and subtle closet staples like her Zara Sequined Blazer ($149), Rebecca Taylor Crinkled Chiffon Tie Front Camisole ($120) and AG Stilt Cigarette Leg Jeans ($178) in Beacon, the most exciting element of her ensemble is her eye-catching accessories. While Palermo kept the high-street theme of her outfit consistent (both her St. Tropez Sandal ($139) and Studded Clutch ($99) are also from Zara) we think that Enzo Angiolini's Quiz Sandal ($99) and Rebecca Minkoff's Supernova C Ya Later Bag ($550) would add a little playful panache to your more basic nighttime fare. -KM, additional reporting by Kelly Agnew
