OK, so lately I've been literally LIVING in baseball tees. They're so comfy and a great alternative to the basic tee. I love the Forever 21 make because they're thin and have a good stretch. Also copped a vintage one from Etsy.com (woot-woot!). They look great paired with hi-waisted flares+kimonos, as well as with army vests+skirts.
