Looking to add oomph to a night out? Take your cue from Chicago jazz babies Velma Kelley and Roxie Hart, whose Roaring ’20s style captures as much — if not more — attention as their murderous crimes throughout the movie musical.

F Carriere carries several styles that any diva would be proud to wear, including a sheer camisole with silver beading ($82.60) and a beaded mesh sleeveless top ($96). It also sells a long mocha silk dress ($192.50) with a dropped waist and an asymmetrical hem, trimmed with silk rosettes and beading. Meanwhile, Anthropologie has an asymmetrical skirt ($128), in black or copper, with a pleated hem and piping detail. And a sheer, dropped-waist sleeveless black dress ($199) with a latte-colored slip exudes the innocent appeal of Renée Zellweger’s Roxie.

"The ’20s look is all about what we do," says Candice Gwinn, one of the two owner-designers of Trashy Diva. Showstoppers at the online boutique include a black silk-georgette dropped-waist tie dress ($180) with flutter-split sleeves and intricate Deco piecing, and an Anna Sui crochet dress ($495) with long-fringed hem. You can top either off with a black velvet opera coat ($425). Modeled after a 1920s New Orleans original, it has a high ruche collar, gathered sleeves, covered buttons, and white silk-charmeuse lining.

Skip a flashy silver dress in favor of a striking metal mesh bag by Whiting & Davis, which manufactured the ’20s originals. Trashy Diva offers five Deco-licious styles ($125 and $150). And Eziba has a flapper-worthy garnet velvet purse ($39.95) with beaded flower details and dangling beaded trim.

It’s easy to get the smoky look of kohl-rimmed eyes flaunted by Catherine Zeta-Jones’s Velma. But Paige Dalton, makeup artist at Sephora, says you should keep the drama limited to your eyes to avoid looking like a clown. "Color lips subtly so they don’t compete with your eyes," stresses Dalton, "and use highlighter and bronzer to bring out the contours of your face." To do this, Dalton recommends Sephora’s Smashbox "Envy" eye shadow ($16), black Calvin Klein eyeliner ($16), and fake eyelashes (available at any drugstore). Use Benefit Browzing Dark ($22) to define your brows, and Nars "Chelsea Girls" lip gloss ($20) and Smashbox "Flair" lip liner ($14) for a nude-looking mouth. To define cheekbones, opt for Smashbox Lights Hue bronzer ($26), Smashbox butter highlighter ($16), and Artificial Light ($28). All are available at Sephora.

Of course, a fabulous face looks even better peeking out from under a stunning hat. Toppers offers a variety of wool-felt cloches rich in period detail. Some standouts are an Orit Parente black cloche ($224) with red-poppy-and-green piping, and a Christine A. Moore pumpkin cloche ($175) with an abstract Deco petal design and a touch of beading. Less expensive but equally stylish are two Allyssa black cloches ($82): one with petal details and another with black beading and rhinestones. And at Trashy Diva, you’ll find many 1920s styles by Libby Brighton, including "Greta" ($145), an ivory felt cloche trimmed with black grosgrain and vintage jet rhinestones.
