Gaga tweeted Sunday that she bought 55 pieces in the sale administered by Julien's Auctions and said she plans to keep the items "archived and expertly cared for in the spirit and love of Michael Jackson, his bravery and fans worldwide."
Auctioneer Darren Julien said the jacket Jackson wore during his "Bad" tour fetched $240,000. Two of Jackson's crystal-encrusted gloves sold for more than $100,000 each, as did other jackets and performance costumes.
The auction featuring the collection of Jackson's longtime costume designers Dennis Tompkins and Michael Bush raised more than $5 million. Some proceeds benefited Guide Dogs of America and Nathan Adelson Hospice of Las Vegas.
