They had a elbow length/3/4 length pocket tee that was kinda sheer in thick red and white stripes at F21 when I was there today. It was cute. Also very cheap!
Technically I bought the s/s one from Ebay, but I might prefer a 3/4 sleeve one instead, since it's cold here in October. Ranchera, do you have a link at all to that F21 one? I'll be at the store this weekend too, so I'll look IRL as well!
