"#tbt to last weekend on the #lake :) #nomakeup," Winter captioned the stunning shot, which showcases her perfect skin.

Winter has earned raves — and raised some eyebrows — for photos she shares of herself on social media. A vocal champion of body positivity, the actress recently fought back against online detractors who shamed her for wearing a slinky dress to her high school graduation.

"Dear sorry body-shamers, I looked HOT in that dress. And if you hate it, don't buy it. But please get a hobby. XOXO Ariel #EmbraceYourBody," Winter tweeted.

That came just weeks after online critics disapproved of the lacy black mermaid-style gown the actress wore to her prom.
