Chrissy Teigen's Date-Night Dress Is Out-of-This-World Sexy

After stepping out to support John Legend at the Sundance Film Festival in Utah, Chrissy Teigen is back in New York, showing off her sexy maternity style. Clearly, Chrissy and John had some fancy plans lined up, because the always-stylish couple coordinated very dapper looks.

While John's tuxedo was complete with velvet lapels, matching loafers, and a bow tie, Chrissy dressed her baby bump in a formfitting black Kaufmanfranco design that featured a cutout and a patent-leather panel on the upper bodice.

Though Chrissy did flash a bit of underboob, she managed to keep her look classy, accessorizing with a Rauwolf emerald gem clutch, simple Stuart Weitzman heels, and silver jewels.
