How many shoes should a woman have? Is there a list of essential shoes every woman needs to have in her collection?

Well, I certainly believe that a woman can never have too many shoes. As a self-proclaimed shoe lover, I can’t stop expanding my ever-growing collection of footwear, which currently counts over 90 pairs.
I have heels, boots, flats, trainers and wellies that I have bought over the years and carefully stored in boxes.
Is this a lot? I wouldn’t necessary say so as I heard about ladies who are proud owners of hundreds of pairs of expensive footwear. I don’t know whether I’ll get there but I certainly know that I’ll never spend a fortune on a single a pair of shoes regardless of how gorgeous they may be.
How many shoes do you have? How many is too many in your opinion?
