Honestly, I'm pretty shocked but it was the around the number I had in mind when I started thinking about this. I would say I do use mainly mid-range products - MAC and No7 aren't cheap, but they're not extortionate. If you were to tally up my skin care, which is mainly Clinique and Clarins, then we might have a much higher number up there! It is startling to see the amount in black and white though. This doesn't account for any tools either - such as brushes and eyelash curlers. I love make-up but I do think I'm fairly sensible with it because I do try and keep the number of products on the go to a minimum. Items like eyeshadow and lipstick, I have tons of but things that will expire, like mascara, I will generally only use two/three maximum at a time. So while that is a massive number up there, I use nearly all those products every day and will only vary the eyeshadow/lipstick.
