Absolutely. Here's my tale:
I bought a mono Pochette Accessoires in 2002. I hadn't used it for several months and figured eh, I'll sell it on eBay. Down the line I intended to put that money towards a Recital which is what I wanted in the first place. Well, the bugger, in excellent condition, sold for mere peanuts (in Jan 06)! What a steal for the winning bidder.
A few months later I found myself wishing I had it back (since I held off buying the Recital) and didn't have anything else in my closet that size.
To quell all feelings of "doing without," here's what I did:
I bought the Recital in April, love it. But I still wanted the pochette. So, I spent countless days and weeks scouring eBay. Alas, I found a better pochette accessoires: the Cerises.
My tale of woe happened to turn out well. However, if it wasn't for this forum with everyone's gorgeous bags, I might have let it go and not bought the cerises pochette.
