I'm curious if boys like bows on girls. I think they do, bows are cute and feminine, a little bow on a hairband or stuck on a clip in a girls hair, what do boys think of these things, matched with a pretty dress, in a 21 year olds hair?
I think I speak for all men when I say...we like vaginas...steel vaginas...and bums...and breasts...(and the odd freaks, feet :s) everything else we're extremly imparcial about and tbh, we haven't given much thought about either. :-/
Works better with younger girls like 15, 16 because they tend to be affiliated with cheerleaders. It might come off as childish on a 21 year old but I wouldn't care if it was feminine or not, since it's your body and you can do what you want with it.
I'm not sure if you would want to wears bows at 21 to look cute; there are other ways. I even thinks bows at my age is a little bit tacky or 'little girl-ish". I don't think at 21 you want to be seen as immature or what ever it may lead people to think. Just think about jobs. Would you rather hire a 21 year old who likes to wear bows and ribbons and all of that or some one who looks at least a little bit professional?
