Look chic and sexy like Chrissy in a black swimsuit

Chrissy Teigen might have had a baby this year, but you would never have guessed it.

As she paraded around in a swimsuit while holiday with hubby John Legend in Mexico, we couldn't help but be floored by Chrissy's figure. She looked utterly stunning in her simple swimwear.

The black one-piece although modest in color, was slung low at the sides, cut high on the leg and scooped at the back. For an all in one, it really did show off a lot of flesh!

The pick is by American Apparel and has also been spotted on Kendall, Kylie and Khloe as well as Selena Gomez to name a few. It's clearly a popular pick.

Gone are the days where a one-piece was a way of covering up on the beach and long-gone are the tummy control panels and simple sporty cuts. Now it's all about the scoop sides, thigh-brow cut or pretty embellishment on these bad boys. The swimsuit is back with a bang!
