hmm darling this is the nature of epsom don't over stuff the bag or the shape will change pushing the beautiful returnee pipping out making the bag look like a football.... the creases are rather good because they will help the bag either bat wing or wear semi/Ferme perfectly. also may i suggest keeping it stored with a bag organizer because once epsom sinks in towards the center its not the best effect on epsom, bags.
enjoy and let her evolve naturally they really do know what they are doing at H. epsom included.
