Great shirt
I love this shirt and although it is see through a tank works great under it to wear to work. the buttons on the back are sewn on really well and it comes down far enough/ is not too short. i am about 5'4" and 100 pounds. the 00 was tight on my neck so i kept a 0. otherwise the 00 would have fit fine since its a blousy shirt and would not have been too tight in the shoulders or armpits.
