[LS] yfBottom_EP16UnderwearTrim Using Wrong Frame for One Swatch

I had a student walking around campus in the male undies with her middle missing, and I was horrified lol. The male version ymBottom_EP16UnderwearTrim is tagged so it shouldn't turn up on the "opposite gender" and I think it should probably be tagged as restricted by "opposite frame" because there's a separate mesh for each.
