Hi everyone, I've purchased a Gucci Disco Soho in the private sale in Sun Orange and I love it, but recently I've noticed a mark (scuff, cut?) on the front which won't come off. The mark is pretty small and not noticeable when I'm wearing the bag, however now I'm fixating on it and it's really annoying. Also, the stitching looks a bit off on the shoulder strap - is this normal? How does yours looks like? And lastly, I feel like the zipper is not really smooth. Does this get better with time? What would you do if you were me? If I return it I'm almost certain that I won't be able to get another one.. Many thanks!
