QINOL Parks & Recreation - Lil' Sebastian T-Shirt Heather (L) Grey

Im 5'8" and pretty thin. Should i go for a small or a medium?

Hi!, may i ask where it is made? what country? any questions that is related will help.

How big is the 4xl? I'm 5'10 with a 29 inch waist and I'd like it to be pretty over sized.

I'm 5' and about 160lbs, and I want it to fit loose, so what would be the best size for me?
