Ariel Winter got all glammed up for a family wedding with her boyfriend of two years, Laurent Claude Gaudette.

The Modern Family star wowed in a white bodycon dress and a bold red lip, while her beau wore a sleek suit.

“My Czech shmooey spending a weekend with us Greeks for the wedding,” she captioned her Instagram of the couple Monday.

Earlier, she shared a photo of her cousin’s first dance after the nuptials.

“The most beautiful bride and groom!!!” she wrote. “I feel so lucky to have been a part of this day filled with love and beauty.”

Winter, 17, has been embracing her curves with form-fitting gowns ever since August, when she revealed she underwent breast reduction surgery in June to go from a size 32F cup to a 34D.

“Girls are tweeting me and saying like, ‘Oh, this wouldn’t be accepted where I am, but now that you did it and opened a conversation about it, I can actually like talk to my friends and family about the possibility of this,’ ” she told PEOPLE on Friday at Teen Vogue‘s Young Hollywood party. “Or, ‘I’ve been living with so much back pain, and I’ve been so humiliated so many times when I had to wear something that was so baggy because I couldn’t wear the things my friends were wearing because it was inappropriate on me.’

“It was just really moving to see so many girls share what I went through and then be considering making a difference because I did.”
