But that didn't stop internet trolls from criticizing her dress.
"Lets [sic] have the hypocritical black dress brigade tell us how victimized they are," one snarky Twitter user wrote.
Incredulously, others mocked her cleavage and said she looked like a "vile [sic] disgusting old hag."
None of those insults went viral. But one tweet from Entertainment Tonight writer Meredith Kile did rack up 120,000 likes (and counting) from people who appreciated a clever reference to Milano's stint as a TV witch on the beloved show Charmed.
"I've never wished so hard that Alyssa Milano was a real witch," Kile wrote.
More of Milano's defenders called critics of her attire "part of the problem" and pointed out the irony of fixating on a woman's clothing during a a discussion about sexual assault.
One thing's for sure: No one can rightly attack Milano for standing up for what she believes in.
