Tuxedo Pants

At the National Board of Review Gala in NYC last night, Anne Hathaway stunned in an all-black Saint Laurent suit, ankle-strap Givenchy sandals, and a patent-leather Jill Milan clutch. Head-to-toe black is always stylish, but we particularly love the tie-bow blouse and dainty lace detail of Anne's red-carpet look. This is the first of a number of award-season events, and if this menswear-inspired outfit is any indication of what's to come from Anne, then we can't wait to see what's next. Take a cue from the actress with a black suit and tie-bow blouse, and then finish the look off with a pair of minimalist sandals, a patent clutch, and sparkling crystal studs.

Jessica Alba bundled up in a military-inspired ensemble that was equal parts cozy and chic while shopping with her daughter Honor in London. She layered up in a black turtleneck sweater, gray tuxedo-stripe pants, and black leather boots, then topped it all off with a navy double-layer coat and burgundy fisherman's cap. The actress complemented her Fall style with sleek leather gloves, a black Gerard Darel shoulder bag, and matching leather belt. Re-create this toasty style by working a chunky black sweater with a knit navy wrap and matching sleeveless coat, then slip on tuxedo pants and black leather boots to nail Jessica's look.

Kourtney Kardashian did some shopping at Hermés in Paris wearing her favorite black leather Valentino jacket ($4,800) and chic black and white tuxedo pants. She toughened things up via these Valentino combat boots ($1,295), then added major luxe via her black Hermés bag. Shop these similar Worthington tuxedo pants ($25), then pair them with your black leather jacket to nail Kourtney's latest look. Wear lace-up boots for comfort and cool, then swap for pumps or sandals for a fancier feel.

Over the weekend, David and Victoria Beckham attended Barbra Streisand's concert at the Hollywood Bowl. Leave it to Victoria to look damn chic in a tuxedo-inspired outfit even when taking in some music. Up top she wore this Lanvin contrast silk blouse ($967, originally $3,870) and a black blazer, then on bottom these Lanvin tuxedo pants ($1,495) and these Manolo Blahnik black patent pumps ($625). On her arm she carried an oversize black patent clutch. Score Victoria's exact top and bottom, or re-create her nighttime look via these less-expensive tuxedo pants ($25) and a silky blouse.

While you may be wary of pairing orange and black together for fear of looking like a Halloween mishap, after spotting Gwen Stefani's latest look, dare to rock the seasonal duo, too. While running errands in LA over the weekend, the singer balanced a bold orange blazer and tuxedo trousers with a basic black top, black leather ankle boots, and a white Chanel tote, then accessorized with blackout shades, a few silver accessories, and her signature punchy lipstick. Re-create Gwen's festive look by working an orange blazer with a black top, tuxedo pants or jeans, and ankle boots for a shopping date with the girls or test-drive the color combo for the office by styling this orange silk Equipment blouse ($198) with this paneled tweed Express pencil skirt ($70) and black pumps.

Olivia Palermo attended the Mulberry Spring 2013 fashion show in London working a burnt orange cable-knit sweater, burgundy tuxedo-stripe Current/Elliott pants ($218), and colorblock pumps. The trendsetter has been on a chic Fashion Week streak lately, but we particularly love the Autumn-inspired color combination of her latest London look. In true Olivia fashion, she took her already enviable ensemble to the next level via ladylike colorblock pumps, a flower-print Mulberry tote, and a chain-link statement bracelet. Pair her exact tuxedo bottoms with a bold cable-knit pullover and colorblock pumps to step into Fall in style.

Kate Hudson was smashing in black and white, donning a contrasting-collar white blazer ($1,895) and tuxedo-stripe pants, both by Alexander McQueen, with embellished Brian Atwood pumps at the Glee season four launch party in LA. Although all the stars that attended looked gorgeous, we particularly love how Kate's crochet black tank injected the right amount of sexy to her androgynous suit. The blond beauty then finished her red-carpet style off with a few Pomellato gold link bracelets and two-tone clutch. Nail Kate's borrowed-from-the-boys look with a few easy styling tips, then shop her exact jacket to work with white tuxedo-stripe trousers and embellished black pumps for a glamorous night out.

Alicia Keys brought a touch of hip-hop to the Edun show during New York Fashion Week in these white side-striped Rag & Bone jeans ($198). The singer paired her black-and-white bottoms with a white button-down blouse, chunky black pumps, and oversize round blackout shades. Her sleek updo, red lipstick, and classic diamond studs complemented her streamlined look perfectly. Shop Alicia's exact denim to work with a white blouse and black pumps for your next fashionable night out or swap the blouse for this red leather peplum Robert Rodriguez top ($495) for a pop of color.
