Fans were left devastated by her premature death from a drug overdose more than four years ago.
A collection of the late star's stage costumes, personal belongings, clothes and awards are up for sale online via Heritage Auctions.
Fans can place bids ahead of the live auction of 24 June and one of the most sought after items is expected to be the custom-made Marc Bouwer gown the singer wore for her wedding to Bobby Brown in 1992 in the grounds of her estate in Mendham, New Jersey.
The gown has a silk mesh overlay which is intricately decorated with iridescent sequins and bugle beads in various elaborate floral motifs.
