I originally purchased the 1x/2x and it fit but the arms were short and tight and the belt barely fit. I reordered in a 3x/4x and the sleeves fit perfectly. I normally wear a 14/16 in jeans and i’m about 5’11. Quality was surprisingly nice. The 1x/2x fit like a large.

It’s cute, but I will say go a size up or a couple sizes, I mean the 1x fits like a large, & I usually can wear a medium or large in clothing. The bottoms still fit like underwear so just be mindful of that.
