The site models could be building a canoe for all I care, so long as there's accompanying measurements of the garment in question. Being in between sizes for most brands has made me treasure the few websites that have actual measurements for each item and not some stupid generic chart for what constitutes a mens medium. Why bother with sizing "help" at all if that's all you're going to provide to the buyer. "OK, so this chart says that at 40" in the chest, I'm a large. So that means I'm a large in Geller and FUBU, right?"
