Are breastforms cringe, or are they acceptable?

So, I made a comment on another forum that I wear breast forms to help me feel feminine. But, one of the upvoted comments was "dont' wear breastforms, they are cringe unless part of a literal drag performance."

I asked why, and was downvoted, while the comment was upvoted. So, I was going to ask ya'll: Are they cringe, or are they fine?
