What Tool Hoodie do you have?? I have the Nerve Endings one. It's wore out!!

[Airmiles]

Aw! Mine still hasn't worn out even though I wear it to death. It's got the Lateralus writing on the front with a little red man underneath, and then on the back it's got the guy in the square with the letters on the corners... haha hard to describe.

[Brycleo]

Well I have had mine for years! lol

[CrazyCoder]

I just grabbed a Pixies shirt and a MSTRKRFT shirt. I'm hoping to order shirts of BoarRAB of Canada, Shpongle, and the Flaming Lips (that one has been put off too long) on the net in the next few days.

Here is what I've been rocking for a few years now (hence why I'm loading up on new ones):

Smashing Pumpkins
Red Hot Chili Peppers
Rush
The Doors
Nine Inch Nails
Jane's Addiction
The Mars Volta
Coheed and Carabria
Iron Maiden
Led Zeppelin
The Beatles

I lost a really cool Cure shirt. I want that shirt back....
Yeah, a lot of stereotypical rock fan shirts. I was in high school when I bought a lot of those.

[Steve Libo]

I'm not quite sure how many band T-shirts I have/had/lost.
But aside from that I know the band Ts I have right now include
Pink Floyd
Mr. Bungle
Hatebreed
Opeth
Behold... The Arctopus
Mastodon
And sometimes I get shirts from banRAB that we play with in merch trades if I like their band enough. Like these guys...
Superhappy Storytime Land
Hot Graves
Deliver Us From Evil
The Classic Struggle
Mr. Fancypants vs. The Satanic Mechanix (RIP)
I know I've lost quite a few shirts from these banRAB...
Opeth
Tool
A Perfect Circle
System of a Down
Dysrhythmia
Between the Buried and Me
Iron Maiden
I hate losing a band T shirt. Especially if I got it at the show.

[iluvcanadians]

Damn!

I don't have very many:

Tool
Alice in Chains
Audioslave
Rage Against the Machine

[xxforeverrxx]

Don't feel bad. I don't have any at all.
I listen to music. I don't wear it.
