Had an extended conversation with a friend about this. She assures me that Schumer is likely telling the truth about her closet currently being filled with clothes labeled 6 and 8. It's just that she and I do not shop at the same stores.  If 125 pounds of female fits into a size 6 in one brand, and 160 pounds of female fits into a size 6 in a more expensive brand, then fuck it, let's just ditch the whole concept of size and start putting length and girth measurements on the labels.
