Yesterday I snapped up an Old Navy tee at the thrift store - the same color and print as the one I've been keeping despite the fact it was too big for me now. Now I can donate the big one and replace it with the smaller one. And just to prove that ON sizing is mental, the too big version was a 1x and the replacement is a L, which is still plenty roomy. Probably could have managed an M - maybe I'll find that one next
