Daphne Guinness' ''classic'' Alexander McQueen possessions are expected to reach their maximum valuation at a Christie's auction tomorrow night (27.06.12).
The Fashion designer is selling a range of designs through auction house Christie and curator Pat Frost believes they will appeal to collectors and to fashionistas because they are ''classic'' items from the late British designer.
She said: ''The dresses and shoes offered here are classic McQueen, so will already appeal to collectors and to fashionistas.
''McQueen and Daphne formed an electrical circuit of inspiration and creation - their Friendship is such a part of the story that pieces created especially for Daphne, like the silver dress, lot 41, are more than the sum of their parts.''
All proceeds from the auction - which was the brainchild of Daphne and Julia Delves Broughton, the sister of Isabella Blow, an English magazine editor and the Muse of hat designer Philip Treacy - will go to the Isabella Blow Foundation, a new charity set up by the heiress to help support young art and fashion talent.
Highlights of the sale - comprising 100 items - include an Alexander McQueen bell-shaped dress, a black CHANEL mini gown and a Christian Lacroix floor-length dress, as well as photographs of the late star taken by Mario Testino and Bryan Adams.
Pat added to vogue.co.uk: ''It has been fun right from the start. We have been so pleased to work with Daphne and her team. Not only was that a pleasure, but, as fashion historians, we have had the added bonus of cataloguing some truly iconic fashion moments.
''Personally, I'm particularly pleased with the interplay of the worlds of art and fashion that these dresses have inspired. Fashion is a contemporary art form, in my opinion, so I am very happy when the wider world seems to share this opinion.''
