I have larger thighs because I Like to lift and they measure at 25.75inches and the classic fit for size 33 is 25.25. I don't want to go up a waist though because I'm a 34 inch waist and the next size up is 36.5 (size 34). So will the Copper (15oz) be too heavy to stretch (and I would need to go to a thinner denim) or will it still stretch?
