Your image should be the least of your worries either way... Worry about sounding good first. Not that you don't sound good... I'm just tired of seeing these punk bands that wear all these vintage designer t-shirts and 200 dollar jeans and put 50 dollars worth of product in their hair... then they can't even play a power chord that sounds decent... Just concentrate on the sound and be yourself. The image will fall into place. Being comfortable on stage is pretty important to me and I'm not about to compromise that by wearing something that's going to crowd my man places...... I stick with clothes that I wear any other time.

Just promise me you won't wear girl jeans, die your hair any obscene colors, or wear makeup...

That's just me though... I'm pretty simple when it comes to that stuff.
