It's not loose tolerances in manufacturing--it's just shitty quality control. Sorry to be so vulgar, but it's true. Tons of boutiques and higher-end clothing labels have almost ZERO variance in sizing. Some of them hand-make their clothing, sure, but most don't. Regardless, though, you're right--there's too much variance in sizing for mainstream brands. This problem really hinders any type of "OpenID-for-clothing" startup.
