In love with old bands? Like ACDC, Kiss, Iron Maiden, The Beatles, Pink Floyd, etc? Vintage band t-shirts look so great and make you look musically intelligent. I have an Iron Maiden shirt.
Sometimes I wear it under a plaid shirt which is a good combination. Or I just wear it plain. HMV and Urban Outfitters sells some band t-shirts and I find a lot of them sold at thrift stores or just a vintage store. Aces High!
