In my opinion this is the best bookshop in London, it stocks all my favourite magazines and has a wide selection of photography books, I spend a lot of my time there just browsing through all the books they have. David Bailey once described the place as “maybe the best photography bookshop in the world”
Cordings situated in piccadilly is a renowned establishment for British Country clothing and tailoring - that can not only kit you out to shoot pheasant in the finest yellow ochre cords but for me offers a great selection of socks.
They mainly sell art and cultural theory books but they also have a good selection of small press and self-published zines. It’s a great place to browse and get ideas.
