Stop in for a cup of coffee

I've been running into issues the last two times I have bought pollo shirts where the shirts fit great in the store, so I get 3/4 of them in various colors etc, only to have them shrink after the second or third wash. Doesn't matter what the material or even the brand is it seems, 100 percent cotton to 50/50. Even double checked the tags. Wife and I are stumped.
Maybe she is returning them for a size smaller?:poke::rofl:
