Curious myself. I've worn mine a handful of times and recently noticed the top sides are starting to "lift". Someone referred to it as bowing. I've seen other WOC's retain their shape perfectly. Disappointed it's happening to mine.
I have the caviar boy woc and I once tried to wipe it down with a slightly damp towel after use before storing it, and some of the black dye came off onto the towel when I wiped the edges. So I'd suggest not wiping it down unless you actually get stuff on it that needs to be cleaned off.
My first WOC! I’ve had this for 12 years! It’s from 10A. I have not babied this bag and have used it sooooooo many times! And it still looks amazing. So the caviar leather has hold up amazingly!!! I did recently take it to Purserehab to have it cleaned (probably could it done it myself) and they did replace the leather straps tho!
