Wang's $8,000 Colour-Change Coat

Alexander Wang´s latest collection is available to pre-order already from Moda Operandi- giving us an early insight into what it costs to create a coat out of heat-sensitive (or, as Wang calls it, "thermo-reactive") fabric.

The coats - which start off a dull green-brown, but become a vibrant yellow, lime, blue or purple when exposed to heat - will retail at $7,995, with a $3,998 deposit required to pre-order.

Sported by Karlie Kloss, Jacquetta Wheeler, Joan Smalls, Kati Nescher and Jourdan Dunn on the catwalk, the coats - already intriguing - piqued even more interest when the high-tech fabrication was revealed. The heat-sensitive skirt and top suit - worn by Hilaru Rhoda, daria Strokous and Anne V at the show - begin at $2,550, and all look similar until their underlying colour is revealed.

But, Wang fans, do not despair. The shin-guard mules - probably the shoe that most editors have been dreaming of since the shows began - will retail at a comparatively affordable $995, while the pocket-covered tunics that opened the show are priced from $895. Although you may just have to be content with their original colour.
