Kim Kardashian Keeping Up with the Hand-Me-Downs ... Bid on My Stuff!

If you've ever wanted to raid Kim Kardashian's closet, here's your chance to do it ... without getting arrested for trespassing.

A bunch of Kim K's old wardrobe and accessories are being auctioned off on eBay right now through marketing agency Auction Cause -- with more than 200 items up for grabs.

Here's the cool part ... a lot of this stuff is "Pre-owned," meaning they were worn or used by Kim herself at some point. There's also a handful of new items she owned but never wore -- such as bikini bottoms. Nothing used in that department. Sorry, creeps.

We're told 10% of the proceeds are going to Children's Hospital Los Angeles. So, at least you're shopping for a really good cause ... besides self-gratification.
