The 29-year-old model looked red hot rocking the fiery hue from head to toe -- especially that semi-sheer bustier! -- at a screening of The Assassination Of Gianni Versace: American Crime Story in New York City.

Chic separates? Don't mind if we do! Unless you're going to a black-tie affair, we're all about taking a cue from Rowland, who partially tucked a white sweater into long burgundy leather Maison Margiela shorts for the Baby2Baby Holiday Party in Beverly Hills. Jessica Alba was also at the soiree, donning a chic maternity slipdress you can see here.

A nude sheath was made party ready with lovely floral embroidery and a metallic belt, as evidenced by Von Teese at the candle-and-fragrance launch of her collaboration with Heretic Parfum, Scandalwood, at Maxfield in Los Angeles.

Sheer paneling met plenty of sequins when Steinfeld vamped it up in this Tom Ford LBD and Christian Louboutin pumps at the Pitch Perfect 3 premiere in Hollywood.

Who says you can't show a little skin at a holiday party? Richie showed us how to do it, smoldering in a long-sleeved mini with a major slit on the left side that was held together by safety pins when she stepped out for an Art Basel kick-off party hosted by DUJour Magazine's Jason Binn and WellNEST at The Confidante in Miami Beach, Florida.

The statuesque model made seven wardrobe changes during the 2017 Fashion Awards, but the most party-ready frock was this embroidered black tea-length dress with floral detailing. 

The fashion icon looked incredible in a black sleeveless gown that featured a sheer skirt at the 2017 Fashion Awards in London, England.
