Tshirthell has the dumbest collection of shirts. I guess if you're a hick they might be for you, but they are definitely not my style and I think I'd be shunned from society here in the Bay for wearing such idiocy.
Hot Topic sometimes has ok stuff, but there is a stigma towards buying HT stuff. They are seen as the "sell out trendy" store. If you like Panic at the Disco or My Chemical Romance, you belong in Hot Topic clothing.
I need some t-shirts too. My diet has been successful and now all my XL shirts are way too big. I had to run out and buy some plain colored t-shirts in L size as an emergency measure.
Are there any sites that sell like event shirts or swag type stuff? Some of my best shirts (that no longer fit right) were for computer stuff and my Otakon shirts. My XP64 shirt was a favorite, and my OS/2 shirts outlasted the OS itself by many years, and have hardly faded!
I check the mall for shirts with nice designs or whatever, but everything they have is so lame. Either they overcomplicate it by sewing stuff directly onto the shirt, or they make it out of some insanely thin or otherwise goofy material that makes it feel like it will fall apart after one wash. I like sturdy cotton shirts!
