I'm not into those big aviator glasses that everyone wears (I think they look stupid and they don't fit my face type). I have a long face and these sporty style look great. Do you think that a good looking guy with sunglasses is more attractive? When I wear them I smile more and have more confidence so that might have something to do with it.
In my honest opinion, It doesn't really matter to me. If they're cheap looking though, then it's not that attractive, but that doesn't qualify into your case. If you like them, that's all that matters. I'm sure you look great in them [:
p.s. I think the aviator glasses are pretty stupid looking, too.
It's not so much that I hate designer glasses on a guy but they aren't very attractive to me. Especially if they look fake or too overdone. Rhinestones or any graffiti patterns are a HUGE turn off for me. Ray bans are amazing though.
