I currently use the W7 palette which is supposed to be a dupe for naked palette. Lately, I've grown unsatisfied with how long the shadow lasts on my skin. I use a primer, but it doesn't seem to help much. This may also be because I have oily skin and it soaks up the product (if that's what's happening). I was happy to spend $6 for this , but is it really worth it to spend around $50 for Naked? Is it very pigmented?
