black dresses

Ashley Tisdale went boho chic in a ruched little black dress and embroidered anorak while shopping with her mom in Beverly Hills. The starlet styled her low-key look with aztec-print Cobra Society boots ($592, originally $845), a leather and tassel CC Skye crossbody ($550), and oversize shades to create a flawless Fall-friendly look. From daytime dresses to layered looks, Ashley's on-trend ankle boots will instantly jazz up any ensemble. Score her exact boots — on sale! — to pair with distressed denim and a chunky knit sweater for Fall, then work them with a flirty maxi when temperatures heat up; the possibilities are endless.

On the Spring 2013 runways we saw a lot of designers pairing dresses over pants, and it seems Emma Watson already took note when she wore a black strapless Christian Dior dress over black trousers at the London premiere of The Perks of Being a Wallflower. The actress completed her unique style with black Christian Dior pumps, a heart key necklace, and diamond stud earrings. While Emma's latest red-carpet ensemble is not mainstream (just yet), we dare any fashion risktakers to follow suit and dabble with the new trend now. For a subtle start, pair a black dress over black pants, then when you feel more experimental, you can play with colors and prints.

Searching for a sweet date-night wardrobe inspiration? Look no further than Anne Hathaway's latest NYC ensemble, where she worked a sleeveless black Dolce & Gabbana dress with chic houndstooth flats. Anne's pixie haircut, oversized cat-eye shades, Stella McCartney wristlet, and simple accessories complemented the cut and texture of her mini perfectly. Channel Anne's polished mod look by donning a sleeveless black shift dress with houndstooth flats or style this printed mod M Missoni ($495) mini with strappy sandals for a bolder look. For a red-hot feel, go for Freida Pinto's fiery mod look.

Keira Knightley stepped out in London with fiancé James Righton in a black and tan outfit that's perfect for a casual night out. Her look included a denim jacket, a black button-down maxi dress, Tapeet sandals, and tan accessories, including a tan belt and a tan shoulder bag. We love how Keira worked her ensemble with ease, then added red-orange nail polish for a touch of much-needed color. Inspired by Keira, sport a black dress with tan accessories and a jean jacket while strolling around the city during day or night or dabble with the black and tan trend via these Rachel Zoe tan leather shorts ($357, originally $595), a black blouse, high heels, and a denim jacket for a dressier feel.

Model and mom-to-be Adriana Lima gets paid to look good, but the brunette bombshell looked absolutely stunning donning a fitted black Amen mini with matching suede pumps at a jewelry event in NYC. Adriana proudly displayed her growing bump in an embellished-collar little black dress, which she styled with diamond drop earrings, a cocktail ring, and a snake-print minaudiere. Pregnant or not, this sweet and sultry look is perfect for date night or a chic cocktail party, so shop our picks below to find your favorite LBD, then glam it up with a pair of killer pumps and a trendy clutch.
