Congrats if the word "threads" means something to you.
Clothes make the man right?... Actually yes. But not the ones you think. I believe that every article of clothing you wear should make some kind of statement about you. Guess what - that Abercrombie Beach Volleyball Team shirt does not say dick about you. Unless you play for the actual A&F beach volleyball team, don't wear this rediculously pompous piece of crap shirt. It sucks. It says nothing about you and chances are it probably smells bad from all that A&F crap cologne anyway.
If you snowboard, get snowboard shirts. If you play lacrosse or football, represent your favorite teams or wear shirts that say you do these things. If you like music, wear your band's t-shirts.
Wear clothes that make people stop and look at them. Find a brand most people don't know about and wear it. A good example is Vestal Watches or Utopia Optics. They make sweet gear for extreme athletes.
Wear clothes that make people laugh or question themselves. Political shirts, funny shirts, and intelligent shirts will start conversation and get you noticed. Check out BustedTees.com. Those Hollister Polo Shirts will be outdated in a year, trust me. Certain brands scream I AM IN HIGHSCHOOL!!! You will not wear these very long. A&F, Hollister, American Eagle etc are all like this.
