lots of glossy pictures in the "fashion in detail" books from the V and A, who have a spectacular couture collection.
i have a couple of them
this one is happily available again after years of being insanely expensive and hard to find:
"17th -18th Century Fashion in Detail" www.amazon.com/Fashion-De...uttmuraa-20

strongly recommend pre-ordering the "20th century Fashion in Detail" book, as once they sell out the prices goes way the hell up
www.amazon.com/Twentieth-...uttmuraa-20

and you can never go wrong with books by Taschen.
"Fashion" 2 volume large format version edited by the Kyoto Costume Institute

www.amazon.com/Fashion-Ta...uttmuraa-20



and ouch. the definitive work on the House of Worth, is out of print, and now up to $400+ as a used book. ouch!
