Ariel Winter Stuns in Sexy Cutout Swimsuit

Now here's a one-piece you don't see every day.

Ariel Winter took to Instagram to show off her daring yellow swimsuit on Sunday, celebrating National Sister's Day at the spa with her older sister -- and one-time legal guardian -- Shanelle Gray. The eye-catching swimsuit style, featuring a large crochet cutout at the stomach, is made by Frankie's Bikinis, and retails for $220.

"Ready to #relax in the #spa #getaway #sister #trip," Winter captioned the sexy selfie.

Last month, the Modern Family star spoke out against her body shamers on social media during her appearance on The Talk.

"I think there are so many bigger issues in the world that we should be focusing on than what we're wearing," she said. "I've been body shamed for just about everything I could be body shamed for... and when I got tattoos... every single person on the face of the planet had something to say about it.

"It can destroy a person, and I think it's disgusting that's what people spend time on," she added.

WATCH: Ariel Winter Shares Racy Behind-the-Scenes Snaps From Photoshoot

In May, Winter spoke to ET about how she's been able to build up her own body confidence, which definitely comes through in some of her racier Instagram snaps.

"I've been through a rollercoaster with myself definitely, growing up in the public eye," she told ET at Modern Family's Emmy consideration event in Los Angeles. "But I think now as I've gotten older... I've had so many people around to help me learn to accept myself and that's been really amazing for me."
