While i was watching at topshop perspex heels i remembered Margiela's glass shoes.
These shoes are entirely made of glass,delicate and fragile like Cinderella's ones.
They are more an idea than real wearable fashion, between fashion and scupture indeed even only one shoe could be bought for exposition purposes. The pair was sold at $2600.
Margiela definitely knows how go over the limit of possible and enchant.
