I'm really annoyed how little consistency there is in sizing terminology. One brand's 'XL' might be too tight for me while another brand's 'XL' could fit me like a garbage bag. Makes shopping online a real hassle for me. I always have to check measurement tables and even then it still might not fit right.
I don't understand why the inconsistency exists. If brands all agreed with each other on what exactly their sizing terms mean, wouldn't that cut down on returns?
