Think you can squeeze into one of Britney Spears' old costumes? Seven of them are up for auction, and the collection is estimated to bring in $100,000! Fork over the cash and you’d get outfits shew war in the "Slave 4 U" music video PLUS the little number she wore at the MTV Video Music Awards! Snake not included. But hurry there are only two days left! There have already been 188 bids…the latest is $99,995 on eBay! Looks like she sweated in them quite a bit.
