i disagree. i find that a lot of juicy runs small, especially in the chest. primp thermals run kinda big, you can def. size down. but i think even when you stay with your regular size, it looks OK b/c i don't think they are meant to be form fitting like juicy. the regular henley style shirts fit mostly true to size (maybe very slightly big) for me. the tanktops ran very small in the chest for me.
Ive been trying to find primp items in the store to try them on. I heard that they run big but I also heard they run small! I have huge boobs so Im big in the juicy jackets so I think ill go up a size?
I usually get a small in primp but it seems to shrink after a few washes, especially their hoodies. Their hoodies seem a bit tight in the chest area and don't stretch too much. As do their tanks. I'd go a size up.
