At the same store where you bought your pants, you will find the bright colours that are a necessity to successful gangsta dress. Oranges, yellows, and greens are especially good. T-shirts are acceptable, provided they have sleeves that reach halfway down your forearm, and that they come at least halfway down your thigh. Sweatshirts should be almost as long, and have either Nike or Fubu emblazoned across the front. Never, EVER get caught dead in a sweater.
Jackets are easy.
For shoes, again, Nikes and Fubus are the best. Reeboks and Adidases are fine for the beginning g'. You might as well forget how to tie knots, because the gangsta who ties his shoes up, gets beat up. It must say Fubu on it, of course. A hat is good, as long as it's got one of the previously-mentioned trade names on it.
