Originally I had to exchange my overalls from a size S to a M, and the process was really smooth. I've lost some weight and thought a S would fit better but it was still a little tight on me and I prefer the loose fit me better - exactly as they say in the description! (I have no doubt if I hadve kept them, the denim wouldve loosened with wear and fit perfect but I still like all my clothes baggy)
I love love love these overalls. I wear them everyday. So comfy and flattering. And pockets are super handy for mum things (mask, phone, keys)
Just love.
