Women's NBA Jerseys
Women's NBA jerseys are cut for a women's fit rather than a scaled-down men's shirt: the shoulder sits closer to the neck and the body narrows through the waist. The women's block is graded independently across every club in the league.
If you are moving between a men's and a women's listing of the same design, size up or down rather than across - the two blocks are graded on different body shapes, so the same nominal size in each is not the same garment.
