I replaced all our hangers over years with wooden ones and not getting wire hangers tangled up or small plastic hangers messing up the shoulders on my t-shirts is well worth the expense. My girlfriend doesn't care, the barbarian, she will throw in a plastic or wire hanger from the drycleaners and I go full-on Joan Crawford https://www.youtube.com/watch?v=XOILKHmZBwc
yah, i bought 100 flat black hangers a few years ago (~$15 at ikea back then) so i could hang all of my casual clothing (rather than folding, which is more time-consuming). the flat ones allowed me to hang like 50% more stuff in the same space. my fancier clothes go on wooden hangers (also ikea) so they have more room to breathe.
