I usually only carry stuff in my Blazer pockets at school, So I'll do that:
Left Breast Inner Pocket: FOX racing Wallet, Locker Key with StrongBadia Stopsign Keychain, 256 Mgb Flashdrive, a small holder of those paper flat mints (sometimes in my Crest Pocket)
Right Breast Inner Pocket: iPod mini, iPod Headphones, iPod Hoodie mini Cover (

Right Blazer Pocket: Papers
Left Blazer Pocket: Papers
Mobile Phone Pocket: My Mobile
