I popped into The Vintage Showroom on my lunch break today and discovered they have a nice looking book for sale. I didn't have time for a perusal properly but I am tempted to go back and buy a copy as it looks really nicely put together. More info here.
"Featuring 130 of the most influential examples of 20th-century and earlier European, American and Asian utilitarian tailoring and design, the book is divided into three sections of sportswear, militaria and workwear, covering everything from 1940s flying jackets and polar exploration suits to vintage French denims. Stunning full-page bleeds and front and back views showcase ground-breaking designs in concept, shape and cut."
