How much laundry?

I recently went three weeks without doing any laundry. I'm not sure what is more embarrassing: not doing laundry for so long or that I have enough clothes to last that long. Granted, there wasn't much to choose from towards the end, but it wasn't like I was wearing rags to work. So is it a good or bad thing that I'm trying to thin out my closet? Do I want to be doing laundry more often?
