Im 5'10", normally 150 lbs. I ordered the large.
I say normally because I'm currently 5 1/2 months pregnant. Because of that I cant button the buttons on the side so ill have to give an update on them after I have the baby. So ill just give my opinion on what I can for now. They seem a bit cheaper than a paor of Levis would but still seem well made. They smell a bit coming out of package but nothing washing won't help. I plan to wash alone or with other jeans because they seem like the type that may leak color onto other stuff.
Ive been wanting to get a pair of overalls for a few years now but had a hard time finding ones I liked. Thats why i bought these knowing I wouldnt be able to wear them right away. I think once they're washed and I can wear them normally, I'll love them. Because of baby bump they look a bit goofy right now
