OP, I feel your pain with your mom. I'm 36, I'm in good physical shape and I've never dressed in things that are very short or tight. My mom classified any skirt above the knee or tank top as "slut clothes." She says it half-jokingly but I know she really feels that way. She's always tried to buy me long ankle length skirts and clothes that are drapery and boxy. I grew up wearing things that were at least a size too big. We're not Mormons, I've never been in trouble for anything, to give her any cause for concern but my whole life she's wanted me to dress like I'm Amish.
