Ariel Winter defends wearing sheer gold dress to 'Modern Family' panel

The actress asked, "Why do I have to be like everyone else?"

Still, Winter -- in a lengthy post on social media -- defended her right to dress however she wants.

"Why TF does anyone care that I didn’t dress casual like everyone else for the panel?" she wrote. "Why do I have to be like everyone else? Why can’t people just let other people feel good about themselves and do what they want?"

The actress then used the opportunity to encourage people to wear what they feel comfortable in, whenever.

"WEAR WHATEVER YOU WANT PEOPLE! As long as you feel good about yourself that's what matters. I now I did," Winter continued. "Don't every let anyone stifle who you are and how you express yourself. Rant over :)"
