I have a 6 year old Marc by Marc Jacobs bag in Purple which I haven't worn in AGES. It's been sat in the back of my wardrobe. I cleared it out today and was really shocked to find that the colour has really faded and the leather has a really dry and cracked look to it even though it is still very soft. What do I do??? I guess the leather needs 'feeding' in some way but can I do this myself or do I need to see a professional??
