(CNN)Chrissy Metz took to Instagram to express gratitude to her fans and to address the backlash over a dress she wore to Sunday's MTV Movie & TV Awards.
Chrissy Metz takes on body-shamers: 'Wear what you want'
"The outpouring of love and support from all of you lovely people has not gone unnoticed," Metz wrote in the caption of a photo posted on Wednesday night that featured her in the much-talked about dress. "I hope that in some small way an unconventional body wearing an unconventional material opened up discussion, hearts and minds."
Metz, one of the stars of NBC's "This Is Us," wore to the award show a deep red custom dress by Jane Doe Latex, an outfit she said was inspired by her desire to "try something different."
Metz fielded negative comments from Internet trolls over her fashion choice. But she was quick to denounce the body-shaming with a strongly-worded tweet late Sunday night.
"For the record, I wear what I want, when I want. News flash it's MY body. #thankstho," she said.
In light of the success of "This Is Us" -- and her character's struggle with body image on the show -- Metz herself has emerged as an outspoken advocate for body positivity. Metz used her latest Instagram post to drive home the message.
"All I'm saying, is do YOU, Boo!" she added on Instagram. "Wear what you want, love you love and treat people the way you want to be treated."
Metz presented the Best Duo award with her TV dad Milo Ventimiglia and "This Is Us" picked up the Best Tearjerker award at the MTV Movie & TV Awards on Sunday.
"This Is Us" is considered a serious contender for this year's Emmy Awards.
