I’m with you here. I had a vintage Diana in amazing condition. And while I loved her, the gold (vintage gold was even more yellow) felt too...well, yellow. It looked good with white but any other outfits felt off to me personally. Maybe because my skin tone is too yellow. But sometimes you just have to go with what you instantly love on you.Yes, sell her. I sold a black lambskin with dark gold bag as I never wore it. It looked so dated to me, and to be frank, I felt frumpy wearing it and stopped using it. Chanel switched to light gold and it's better. I prefer silver as I'm a white metal gal.
I vote to sell it and get one with silver hardware. It will look much more contemporary in my opinion.
