This is wrong.. U dont size down 2 for all.. NC's are skinny not slim! U either stay true to size or size down 1 on NC's unless u are super skinny.. NS isnt relaxed at down 1, they are slim. size 2 is slimmer and 3 is almost skinny.. PS arent NC's, they have more waist and thigh room but are tapered, either size down 1 or possibly 2 since they have room in the thighs..
