“wrong sizing”

“STP stated that a size 32 is equal to a "4" womens. I am a small size 2 and these were snug around the waist. I have seen reviews on other sites that said a 38=an 8, so maybe this was just wrong american sizing. I thought they would be stretchier, but they are a nylon type pant with just subtle stretch to them. Most reviews I read that liked them were not people who were using them for climbing, rather casual wear. If you size them right, could be used for either, but for me, to climb in warm weather I would go for more of a stretch material and a sturdier material for colder climbs. They were nice looking, but the velcro on the inside of the waist not comfortable. I just don't know many climbers that want snug fitting high waist pants. I prefer lower waistline. The material was very lightweight, and do not believe it would hold up on the volcanic rock in Hawaii. I am sadly sending them back.”
