I think Angie has a limited number of hangers and does not buy more than she can fit -- or rather, commits to "one in/ one out."
I just updated my hangers this weekend for the lower profile ones and there were 50 in the box. I have extras, yay!! Admittedly, my skirts and trousers on separate "stacked" hangers, so really we're just talking tops, dresses, and toppers.
