Earlier this summer, she had her breasts reduced from an F-cup to a more manageable D-cup, and Ariel Winter certainly looked a lot more confident emerging for the first time since the procedure.
The 17-year-old actress had been suffering from years of back and neck pain prior to the surgery, which took place in early June.
Wearing a green playsuit, she attended D23 EXPO, a Disney fan event, in California on Saturday to promote her animated TV series Sofia The First.
Ariel is best-known for her role on Modern Family, where she plays teenager Alex Dunphy, although she said recently that her shape caused problems during filming.
Indeed, even standing for extended periods of time was difficult: "It was so painful. I had a lot of back problems.
'I really couldn’t stand up straight for a long period of time. It started to hurt so bad that I couldn’t take the pain.

"My neck was hurting so bad and I actually had some problems with my spine."
She also explained: "They had to hide it on Modern Family a lot.
"Big sweaters, strapping me down – which is fine – I understand that it doesn’t fit the character they have in mind.
"I understand that. But it was difficult to do that every day."
Opening up last week, Ms Winter has said since the surgery that she feels like a "new person".
