I took a risk on this one. i wasn't sure if the shirt was more green or more blue. i look better in blue. it turns out that the shirt is a bit more green, but i think it still looks good! i'm 5'3' and 125 lbs. i got a medium. i could have maybe gotten a small, but i like the medium. the shirt has a bit of a vintage look to it, which i like. all in all good.
