Most Helpful Guy
I think it depends on what type of guy he is. Everybody has their own turn ons... Like some guys might just be the type to like girls who wears mini skitts. Some might like girls that dresses conservatively...
I think it's best that you wear what looks good on you, not based on what you think other people think is hot/sexy. I think if it's your personality and it fits you, it's good.
It's probably best to wear something that shows your best feature
