Lacy, not racy!

Scarlett Johansson (in Dolce & Gabbana), Jayma Mays (in BCBG) and Malin Ackerman (in Chanel) are just some of the stars stepping out in sophisticated peekaboo lace dresses.

To pull off the lovely trend, opt for a collarbone-skimming necking and just-above-the-knee hemline. "This keeps the look from being too provocative," explains Mays' stylist Ilaria Urbinati, who suggests accessorizing with nude heels, minimal bling and a good slip.

"Make sure everything is lined!" she says.
