So I have 10 and am working my way through them. It's OK IMO to have a wardrobe of scent, day, eve, Summer, Winter. Some I'm actually trying make last longer like Alexander MacQueen's Kingdom. If there any that you just never wear and never will either gift-on or sell on E_bay, discontinued fragrance has been booming.Had to do this a few years ago my mother gave me some Ltd Ed. Lalique miniatures and I was not keen on the fragrances, I was shocked how much it went for - huge market.Yeah, if anyone can give me advice on what to do with my vast collection of perfume, please do.
