The English version of the Tassenmuseum is http://www.museumofbagsandpurses.com/
but the site can be very slow.
Tied-on pockets & inside pockets (unless extremely small) weren't worn much past hoop era bec., as you noted, they ruin the line of the skirts.
For bustle, 1870s-80s, you have lots of purse options! Small round fabric bags (aka reticules) are still used, & small structured leather bags are becoming very popular too. You can prob. find something at a thrift store/eBay/mall accessory store that would work for the later. Think 'miniature suitcase' in particular for daytime.
Metal frame purses are documentable to the 14th century & were used thruout the 19th century, plus they're fairly easy to make. Materials can be cheap -- you can find simple frames on eBay or, better still, rip apart ugly thrift store purses! My pattern & instructions are here
, you just need to modify the pattern to fit the frame you find.
I have lots of purse images on my computer at home - I can go thru them tonight & send you some 1870s ones if you like.Edited at 2011-06-13 04:51 pm (UTC)
