The "Modern Family" star took to Instagram on Wednesday, where she showed off her fit bikini bod while modeling different swimwear options for her fans.
"For #springbreak or nah?," she captioned the cute video.
In the clip (below), Winter rocks a colorful chevron-printed string bikini as her newly-dyed strawberry tresses are styled straight and parted to the side.

The 18-year-old beauty definitely got plenty of encouragement from her fans on the social media site, too.
One user wrote, "Body goals! You look awesome," while another posted, " Love your bathing suit! And seriously body goals! You are such an inspiration to me, wish I knew you in person!"
It definitely looks like the actress has become much more confident since opting to have a breast reduction last August.
The photo comes after Ariel staunchly defended Kim Kardashian's nude selfie last week.
"I think everyone, men and women, should have the right to choose what they do with their bodies -- and not be criticized," she said at the time. "No one was body shaming @justinbieber when he posted his nude guitar photo so why @KimKardashian? #herbodyherchoice #InternationalWomensDay."
She later posted, "Do what makes you happy. Do what makes you feel strong. If it doesn't harm others, there's nothing wrong with it."
As thanks, Kim actually sent Ariel flowers, along with a note reading, "I wanted you to know I saw your tweets last week and I really appreciate your support. Women supporting other women is so powerful."
