Princess Diana during her lifetime was a fashion icon and even after her death, her prized possessions have been valued by many. One of the late Princess of Wales' most valued pieces – a glittery Catherine Walker gown – is up for auction. The blue dress will be auctioned off by The Saleroom and could fetch anywhere between £80,000 ($115,000) and £100,000.

The Saleroom, which is an online antiques dealer, will accepts bids for the iconic dress on 14 June. Designed by Walker, a close friend of the late Princess; the sequined dress was worn by Princess Diana during her state visit to Austria in 1986 and four years later at London's Diamond Ball. With slightly puffed-up full sleeves and a front slit, the gown sat beautifully on the ever graceful Princess whenever she donned it.

This is not the first time the iconic evening dress will be put on sale. Back in June 1997, Princess Diana had herself auctioned her Walker gown at Christie's in New York City – just months before her tragic death in Paris at the age of 36. The gown was sold again in 2013 for a whopping $131,000 at Kerry Taylor auctions.

Apart from the late Princess' shimmery evening gown, another outfit will also be up for grabs – a teal wool tartan Emanuel B couture coatdress.

Priced affordably as compared to Princess Diana's blue gown, the wide sailor collared, box-pleated Emanuel special dress has been listed for a starting price of £10,000. The Princess was pictured wearing this coatdress during her trip to Italy in 1985 accompanied by her husband Prince Charles and sons William and Harry.
