Katy Perry, Rihanna, and Kelly Osbourne take a turn about the red carpet at the Grammy Awards.

Just because we have New York Fashion Week on the brain doesn't mean we've forgotten to check on the Grammy Awards' red carpet. Hardly. We've taken stock of who wore what and how, and we're pleased to report: blues, blacks, golds—whatever your sartorial pleasure, the ladies at the Grammy Awards have got you covered. Prefer barely-there or covered-up? You're also in luck.

Singer and false eyelash entrepreneur Katy Perry matched her hair to her sky blue Elie Saab gown, a scoopneck, belted number from the Spring 2012 couture collection. Ladylike and refined to be sure, but Perry's ever-changing hair color kept what could have been a too-stodgy (yet lovely) turn for the rock 'n' roll red carpet cheeky and playful.

Meanwhile, Rihanna's mutual love affair with Armani continued in a cut-to-there—neckline and leg slit—all black number, at once sleek and super sexy, a boldness de riguer for the "We Found Love" songstress. A gold clutch and simple jewelry plus Christian Louboutin  PVC-accented pumps rounded out the sexy look.

Former Material Girl face Kelly Osbourne turned golden girl in a one-shouldered Tony Ward floor-length gown from his Spring/Summer 2012 Pret-a-Porter Collection.

Evening winner Adele and Kelly Rowland

Before sweeping the ceremony with a six-award win (and the first live performance following her vocal surgery), Adele didn't deviate from her preferred Old Hollywood aesthetic. And why would she? The three-quarter sleeve Giorgio Armani floor length gown coupled with a slash of red lipstick, bold eyeliner, and voluminous hair is a consistent, winning look for the current Vogue covergirl

Kelly Rowland's nude Alberta Ferretti gown with sheer paneling and silver floral embellished bodice brought out the big guns, showing off her svelte physique and sleek pulled-back curls.

Taylor Swift, Chrissy Teigen, and Lily Aldridge.

Known for the frothy gowns and ethereal curls that grace nearly every red carpet appearance, Taylor Swift smoothed back those bangs and took a more grown-up approach to the ceremony. Trading in strapless mini-dresses for a Zuhair Muhad high-neck, mermaid number, Swift's ensemble was a welcome twist to her always refined and glamorous gowns, adding Prada shoes and Neil Lane jewels.

Did Sports Illustrated swimsuit model —and John Legend's paramour—get dressed with Rihanna? We've seen this all-black number before, the slit too, but Teigen's more covered-up—no decolletage in sight— variation remains a stunning, no-fail twist to the L(ong) BD.

Mama-to-be Lily Aldridge showed her support for hubby Caleb Followill (of Kings of Leon fame) in a purple, black, and grey floral long-sleeved gown. The Victoria's Secret Angel showed no signs of slowing down her stylish edge as she switched her beloved Vera Wang for Gucci.
