I...I don't think you can find even those corny "God Bless America" tees (made in China!) for that much. >.>;
Anyways, I highly suggest thrift stores like Goodwill...you'd be surprised at what you can dig up. I once found a gorgeous velvet duster-vest under $12 at one.
Even if you don't find exactly what you're looking for, you can always find something to modify.
