From photos of a lot of pearl crushes they look more wrinkly than classics, so it's probably within the realm of normal. I'm more concerned about the flap looking crooked in some of the photos and read that pearl crushes in general have very delicate leather, getting worn out corners and edge of the flap within a handfull of wears, and this is a white bag. If these things don't bother you and the only concern is the wrinkle, I'd definitely keep it! Good luck on your decision
