I definitely need to do another pass of my closet in the near-ish future. My problem is that I've weeded out enough in the past that I do need to replenish "staple" clothing like tank tops and plain black t-shirts but still have basically nothing for certain events but sure do have sweatshirts I never wear.

Maybe consider what you need, clothing-wise, for daily use and events and if something does fit with a need category, then it's okay to bring in.
