I'm 18 and I've always dressed in a "relaxed" way, jeans with a t-shirt or a sweatshirt. But as I grow up I'm starting to like suits more and more. I see my self wearing suits daily in a few years (probably as soon as I finish university). And I was wondering, so girls like guys on suits?
I wouldn't fall for a guy based on what he was wearing, but yes..when a guy I like puts on a suit, it's the icing on the cake for me, especially if it is black. Suits say power, leadership, authority. A lot of women find these traits very attractive in a man. For an informal occasion you could try a more casual blazer with jeans.
I think if a guy is attractive, he's attractive no matter what he's wearing. But yes I do like suits on guys because it makes them look put together. It also gives others the impression that he is a strong/powerful and in control individual (think James Bond, on Sky fall 007). If you love suits hey go for it, I'm sure you will still get girls, if not more than you have in the past! ;)
