I don't have a vanity. I keep my skincare items in a train case on my bathroom counter. I also keep my "finishing up" products in there because I apply 99% of my make-up in my bedroom but then I go into the bathroom to use my setting powder, bronzer, lipstick and setting spray.
Most of my make-up is in a faux leather cosmetic bag that rolls open and once open there are 4 individual pouches where I have things separated out. It's like the Joy Mangano better beauty cases but mine is from Sephora.
On a nightstand, I have my application sponges in sponge holders and I have 2 ceramic brush holders that are full of brushes. I have some larger compacts stacked there and a few different mirrors.
I seriously did a declutter several months ago and got rid of make-up items I didn't use. Out went foundations that didn't suit me or I didn't like for one reason or another, eyeliners got tossed, shadows I didn't like, etc. Many products I only have 1 of, like bronzer, setting spray, setting powder and a few other things. I just don't see the need for options in these types of products. I don't own a ton of blushes either because again, I don't need them.
I have a couple of large shadow pallettes and now I've gotten into really liking a 1 and done shadow look so I'm not even using that much shadow. My lipsticks are totally ridiculous.
