the other thing is, 36 from brand Y isn't the same as 36 from brand X. you'd think it should be, but it isn't. not to mention, with the whole mass production thing, i always think someone messes up somewhere, and you dont actually get 36x34 even if it says that on the label. (for women, i dont know why there is a size 0, which isn't 0 at all. that makes no sense! it should be 1 or greater! heh)
that's one reason why some people fall in love with a certain brand of clothes.
