Ariel Winter has been on a sexy style roll lately, and her latest look may be her most risqué yet.

The 18-year-old "Modern Family" star just graduated from high school last week, and she wore an incredibly revealing light pink dress to her graduation party that put her signature curves on display.

In the snap, Winter is seen posing next to a dessert table with her hand on her hip and her newly-dyed, red locks look amazing. The true focus of the photo, though, is the insane amount of underboob that the young star put on display in the cut-out dress.

"I couldn't be luckier or more grateful," Winter wrote in her caption. "I was in awe last night and I still am that you guys love me that much to do all of that for me...I never would be where I am today without you guys saved me and taught me to be the person I am today."

Calling out her father and sister for throwing the gorgeous party for her, Winter gushes about her family and the support they've given her through the years.

"Thank you SO MUCH to all of my amazing family members and friends that flew in to celebrate with us," she continued. "You guys are the absolute best. Thank you also to the ones who didn't have to fly in ... so much love was felt all around last night. Thank you."

Congrats to the graduate! She's be headed to UCLA in September.
