This brand runs small and has a fashion fit, most customers order a size up from their normal size. See the size chart here under the listing for 'WOMENS': http://www.americanapparel.net/sizing/default.asp?chart=womens.shirts
Multiple sizes available in unisex and womens - please see other listings. Heather gray color may be slightly lighter or darker than photos due to differences in dye lots.
If I am out of stock of the size you need, send me a message with your email address and I will add you to my mailing list so you can be notified when they are restocked. Thanks!
