Tailor in London?

[idioteque//]

Hi guys,

A friend of mine needs to get a suit made for his wedding so... we are looking for a good tailor. Saville Row prices are a bit over the top so I'm looking for something a bit less pricy.
I heard Paul Smith and Comme du Garcons are working with a tailor in Covent garden... but I forgot his name...

Any help would be great.
Thanks
Kelly
