I just try to buy the same thing once I find something that fits, is comfortable, and lasts. Got so I keep a little note file. That doesn't mean I can find everything again, but it helps.
That's me. Find pants that fit grab 5 pair.
Find a shirt get a half dozen different colors.
Foot wear though us a different issue.
I have about 75 pair of sneakers alone and maybe 3 dozen dress shoes.
