T-Shirts Slimmer than Old Navy

[Lee Saxon]

So, I'm a photographer doing a lot of location work, and New Orleans is hot, so I wear a lot of casual, inexpensive t-shirts (not undershirts, graphic tees). I've been working out and losing weight and I'm getting to the point that the Old Navy Larges I've been buying are a looser torso fit than I'd like. But my shoulders are too broad for their Medium.

Any suggestions? Doesn't have to be quite as cheap as Old Navy but don't give me Givenchy
