In 2011, fashion has proved to be faster than at any time in history prior to now - technology has seen to it that all forms of design, production and distribution are smoother and more efficient than before.
Fast Fashion means that events like the recent Royal Wedding become as much a fashion spectacle as anything else - with bloggers and fashion sites picking up on the style minutiae of the event - even the bride's sister's shoes caught the attention of many.
How fast can fashion get though? Well, don't expect it to slow down any time soon. In the future fashion could even be real-time - or close to it - when 3-d printing comes of age. 3d printing is an amazing process where products are built up layer by layer in (you guessed it) 3 dimensions - amazing stuff. I don't think it's been used for clothes yet, but it's likely that one day it will be.
In the meantime - enjoy the speed of fashion, since it's something that was unavailable to previous generations, who had to wait months for on trend affordable gear to hit the shops.
