I really don't have a limit or minimum for clothes really..... I don't really shop that often so once I find something I like, I get it, but I won't go shopping again for like 5-6 months at a time if not more. Basically all I need is clothes for home, clothes for work, and clothes for church.
The one thing I do overindulge in sometimes is accessories. I have a lot of little plastic costume jewelry and way too many scarves.
