YSL's Ombre Solo Lasting-Radiance Smoothing Eye Shadow does exactly what it's name suggests. I tested this product without using a primer and then spent the day running errands in the heat and humidity. This eye shadow stayed put and looked beautiful all day long.

It comes in a beautiful tiny golden compact plus two applicators so you can adjust your look easily on the go. The case is reflective enough to double as a mirror if you're in a pinch.

I usually shy away from mono eyeshadows, as one shade generally isn't enough for whatever look I'm aiming at for the price you pay. I have this product in "Fawn", which is a tawny goldy colour that gives a sunkissed look. In this case, I happily make an exception to my rule.

Great product!
