I think I went a bit overboard over the last month and bought a whole heap of shadows that I don't think I will be using much. I might have a blog sale soon!
Not sure what other people have in their collection but I don't think I need that many eyeshadows unless I do this for a living! I actually bought a whole heap of eyeshadows and pigments (all MAC) from ebay. It was a huge package deal and I thought I will be saving heaps of money but now I'm thinking, would I really buy all these colours? Nope! I wouldn't. So it was a waste of money. I don't even use pigments much - I find them a bit messy. But they come in great colours! After that huge purchase, I got a bit of an online shopping frenzy and bought more eyeshadow palettes on ebay. Till this day I think I touched 4 shadow colours from the palettes.
As for lipgloss- that's a another story, I think I keep buying the same colours without realising that I already have something similar. I got about 30 right now and you only need a pink, red, peachy, clear and maybe a nice shimmery one. There are a lot of repeats!
I better take a photo of my collection each time I go shopping so I know what I have already!
By the way, I have a two drawers full of MAC shadows that need depotting, anyone have any tips on where to get cheap empty palettes?
