Most Helpful Guy
Does it define them? No
But it does potentially say a lot. First impressions do matter, and one of the things that's taken into consideration besides just someones physical appearance I'd the way they present themselves. Sure it would be nice to give everyone a chance reguardless of that but there's only so much time, so one must be selective and ocassonally make judgment calls based on initial impressions.
So if I see a girl that dresses/presents herself like she works at hooters or just wears really revealing clothing, I am going to assume that she's potentially insecure and seeking attention, and that she's potentially wild and sleeps around. Are those assumptions nessesarily correct? No but they might be.
Same thing for guys, if a guy wears really low hanging jeans, a wife beater and a baseball hat or lots of black leather and numerous piercings. You might write him off oru assume he's potentially lacking intelligence and not the loyal relationship type. However if you see a guy dressed more formally you might have the opposite impression.
Are your assumptions accurate? Who knows but you make them. Fact of the matter is the way you present yourself does affect the way other perceive you.
Personally I think balance is key, the middle path is usually the best. I don't really like girls who look like they are part time strippers, they just give off that promiscuous vibe and that they need/want the attention to feel better about themselves. However I'm also not really into the girl thats ashamed/scared of her body to the point she's dressing like a nun.
The best is a girl that's comfortable in her own skin to the point where she can show a little skin but at the same time she doesn't feel the need to "give it all away" she knows how to leave a little bit to the imagination" so that her looks gain your interest but if you want to see more you've got to work for it.
