I work on costumes a lot whenever I visit my parents because I don't have a sewing machine. I usually show up with entire pieced and pinned outfits, ready to buzz through all the seams in a few hours. That means my parents always get to see at least the clothing parts of my costumes.
Last year, I was Emma Frost. Very midriff-baring, cleavage-showing, et cetera. My mom loved it, and actually helped me fit the top. I also did Dagger last year, which she didn't get to see, but which is even more revealing. This year, they got to see me work on Rogue, and my mom was amazed that I was making a costume which, as she said, "your father might actually approve of."
