Diesel is nice, Azzure Denims. Find your own style. If you're in your mid-20's and you want to accomplish a more put together, ambitious look (which denotes social power and attracts more high esteem women), start looking at button ups and some frame fitting jeans with nice classy shoes.
Ultimately, your look and fashion should be a sort of catalyst to where you ultimately want to go in life. Just as the way you talk, walk, interact, and think sends out to the world what you're about, and attracts accordingly, so should how you dress send out the same message. If you're trying to attract high school and college aged chicks who're into partying and just looking for a cute guy for fun, dress accordingly. If you're looking at moving toward more sophistication, the same rule applies.
It actually sounds a bit philosophically inclined what I'm talking about, but everyone's style's different. If you're asking some other guys about what looks good on you because other people are saying that the popular brand A&F looks fruity, then you really need to check why you're looking for a new fashion brand.
But, to be fair, check out some fashion mags and see what guys are wearing on there. Whether it be GQ, Men's Health, or other various mags. Check out what styles fit with you, and adapt accordingly.
Hope this helps !
