There is a glitch within Bully that allows you to hit a Cop or Prefect without them being able to get to you.
There is a wooden bridge across the entrance to Bullworth School. If you jump onto the hand rails of the bridge while the authorities are after you and shoot at them from there they can never get you. They try to grab but can't get you due to the glitch.
During dodgeball, press L2 to bring up the help screen right before an opposing player has the ball. While the help screen is up, your players will be not be knocked out if they get hit. The ball should bounce harmlessly off your player, allowing you to pick it up and go on the offensive.
Once you complete the requirements for the clothing, they're automatically thrown in your closet, in all your safehouses.
Final Cut (New Coventry) houses all of the punk-esque items in the game. Worn In (Bullworth Town) houses more beachy, sporty, and middle classy type clothing. Aquaberry in Bullworth Vale houses all the upper crust type clothing, although until Chapter 3 the only clothes you can get in there are the Aquaberry Sweater and Vest.
