Order one size bigger than what you think. I LOVE these, but they were a size toooo small. Coming from overseas, exchange woulda been a be-atch.
I was thrilled to find such an authentic-looking pair of blue jean overalls like my grandpa wore on the farm. They are tighter-fitting than other overalls I've tried and wouldn't work over your clothes. I'm 5'7"/183 lbs and wear a 40S jacket/34 inch waist in vanity sizing. I bought the XL and they are very snug around the middle and the fly is comically high to the point of useless. I wish they were a little better made—the clasps were loose before I tightened them with pliers—but for the price and the aesthetic, I am very satisfied. Very cool look. They are probably better for fashion than work, but I have worked in them without issue and I got a lot of compliments while doing so!
Nice weight to the denim. The "crotch depth," where the waist falls to the bottom of the crotch area was tight for the size that should've matched to me. I should have been a L, but that area was way too "tight" so had to get an XL. Would also suggest reading their return policy before buying, it's very different than US retailers.
