I got a LE Orchideal and one of the handles got wrinkled after 2 uses. What I did was I email their customer service and they are so quick to reply to me and even allows exchange for a new one as it was only 2 weeks old. Sad part is, since it was a LE released in 2012, my local Longchamp boutique doesn't carry it anymore, so they offered to replace the handles with an original one instead.
I don't have the receipt or any proof of purchase though, I just sent pictures of the bag including it's inside tag, and from there, they said that, the details I provided are already enough for it to qualify for their after-sales service!
