i've had a read of the leather thread in the reference section about courchevel and since it's similar to epsom, i was assuming that it'd be pretty rigid. however, whilst browsing eBay, i chanced upon a birkin in courcheval (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ih=020&sspagename=STRK%3AMEWA%3AIT&viewitem=&item=300111011304&rd=1&rd=1) and the seller described the leather as having turned very soft and needing stuffings to stand alone. As such, i was wondering just how sturdy courcheval really is and whether it's normal for it to soften/sag so much overtime. moreover, is there perhaps any way to maintain or upkeep the rigidity of the leathers or is it a lost cause? i'm looking at getting my first birkin from paris (with some luck) and would really like a more rigid leather. it seems like vache liegee would be fit the bill, but are there any alternatives besides that and more importantly, how much slouch would i be looking at, over time? thanks in advance, everyone.
