If you're in the Atlanta area, there's a storefront there, but it's the closest one to Nashville. Otherwise, you gotta go online or there are some basic selections at stores like Dillard's and Macy's. Alternative also has tons of guys' tees and hoodies, and what they do so well are those basic neutral colors that guys and girls love. And they look already lived-in, which means you'll have to keep yourself from automatically reaching for them everyday.
I highly recommend this tank, which I own and wear at least twice a week. Alternative does burnout (which I'm totally obsessed with) in a way that's not so sheer you have to layer another tank underneath so that friends/strangers/randoms don't see your business. That tank would be the perfect layering piece under this wonderfully slouchy tee. I LIVE in tees like this. So comfy!
