Here’s your chance to own a little bit of Christina Aguilera fashion history…

Property from the Randi Rahm Archive, an exclusive collection of iconic couture gowns worn by Hollywood‘s elite, including the 39-year-old half-Ecuadorian American Grammy-winning singer, will be up for auction next month.

Julien’s Auctions has announced that the Rahm signature styles that have graced the covers of magazines and waltzed down red carpets will be available for bidding December 2-3, both live from Beverly Hills and online.

The top items featured in the auction include Aguilera’s black satin crepe gown from the 2007 Clive Davis Pre-Grammy Awards party (estimated $2,000 to $4,000), Beyoncé‘s nude fringe embellished dress she wore to first lady Michelle Obama‘s 50th birthday bash in 2014 (estimated $3,000 to $5,000), and Mariah Carey‘s orchid and gray twisted halter silk dress from her 2005 “We Belong Together” music video.

Three more items from Beyoncé’s wardrobe, Carrie Underwood‘s one-shoulder purple satin silk gown from her 2010 CMA Awards performance (estimated $2,000 to $4,000), Katy Perry‘s tie-dye aqua-blue cocktail dress from her 2012 “Katy Perry: Part of Me” Tokyo meet-and-greet (estimated $2,000 to $4,000) and more are also included in Rahm’s collection.

The collection will be available to both bidders and collectors, who must register either in-person at the exhibition or online before the sale here.

The public exhibition at Julien’s Auction is free to the public and open until November 27 (closed on Thanksgiving Day, Nov. 26) at 257 N. Canon Dr. in Beverly Hills, Calif.

The auction will take place from Wednesday, December 2, to Thursday, December 3. Interested parties can place their bids in person, online and on their iPhone app, over the phone with an auction house representative, or in advance via absentee bid. Absentee bid forms are available by calling Julien’s Auctions, checking their website and seeing the back of each catalog.
