Paula, I can't find that * next to the small, which shirt are you looking at? They buy different styles of t-shirts from different manufacturers, so it depends on the style. The one shirt I bought for myself from them is a Hanes Her Way and I think it's about average for being the size it's supposed to be. I can ask them about the sizing if you can tell me which shirt you're interested in. The only other place I see an * is where it says, next to XL, "not available in all styles."The ones I have bought for my husband seem to be the right size.
