I haven't tried this yet, but I've been eyeing some skirt looking bags at Wal*mart that i'm wondering if they can be modded to work. They're only $3 and come in several colors (if anyone's tried one, let me know).
I like the hoodie (just feel like I'm commenting a lot XD). Casual stuff is kind of nice to have, though I don't have a lot for mine atm.
Goodluck on Saber. :3
