I would like to buy a t-shirt in an American site, but i cannot understand what "Black standard 100% cotton heavyweight tee" means, especially heavyweight. Does it refer to a special thick cotton or to the tee shape?
Thank you very much.
"Heavyweight" cannot refer to shape. It just means that this t-shirt is heavy. The inclusion of "standard" suggests that there is a norm for the weight of the cotton used to make a "heavyweight" t-shirt. The implication seems to be that the cotton used in this t-shirt conforms to that norm.
