I thought we could have a general thread where we can request recommendations for products that we are looking for (as far as I know there isn't one already?). 
For example, I am currently looking for a good pencil eyeliner that doesn't smudge. I prefer using pencil liner on my upper lid for a softer look, but inevitably it leaves a line in my crease after a few hours. I don't know if it's because of oily lids, or wrinkled lids or what (it didn't use to be a problem for me). I use eyelid primer, and I know using eyeshadow to set the liner helps, but that's an extra step which annoys me.
So, non-smudge pencil liner (in dark brown). Any recommendations?
