Vanity sizing over the years means that neither men nor women can simply rely on size labels anymore. This is why Woot includes a sizing chart on every shirt’s page. Every brand is different and everybody’s body is different.
I normally buy men’s large in American Apparel for a little breathing room, medium if I want it fitted. My work attire (polos, short sleeves, etc.) range from small to XL, though they all in that same range.
As always, CHECK THE SIZING CHARTS!
(If the sizing your ordered differs from the chart, write into CS about it.)
My apologies, but I am not aware myself as to why this has been out of print for a year now. Maybe someone from the Woot team would clarify.
Thank you for liking this, and sorry again for it not being available when you wanted it.
