Do you like plaid? If you're a guy of a certain height, I sure hope so, because most of the clothes available to you will involve that particular pattern.
Eddie Bauer has plaid. They also have a great selection of shirts in men's tall sizes (they may have tall women's sizes as well, but I didn't look at those). This location is an outlet store, so they had lots of stuff at a discount. I bought two shirts for about $50, which isn't bad, especially when you're used to being price-gouged for tall clothing. The only flaw this store has is that they don't carry 36 length pants. Those are available on their website, however.
If you're looking for that coveted size T, check out this place. It's one of the few things worth the trip to Concord Mills.
