Lemme tell you something boy, hair style and clothing are not that important (not at all) if you have some meat on yourself (muscle). Many of my friends have shitload of shirts and try to keep up with fashion, they always have new haircuts, but when you have pipe arms, small cage and skinny legs, one thing is certain, you won't get in relationship with hot girl that's for sure.
If your skinny or fat, clothing doesn't matter, because people are not blind. And again they first notice your body, then your hair and clothing.
Of course, if your big but retarded. Then, no one can help you, not even gym.
It all depends, but, if you're good, smart guy and have something to show behind t-shirt, any girl is yours!
