YSL fall was a disappointment for me - I checked out the new colors (except the gloss volupte which they did not have yet) and came home with 2 items, and then returned the eyeshadow duo the next day. The remaining colors just weren't me, and didn't seem coordinated at all.
Pictured below Ombres Duolumières #23 Pearly Peach-Mink Brown and Crème de Blush #02 Powdery Rose:
Swatches, #02 Blush on bare skin, #23 Eyeshadow Duo over Laura Mercier Eye Basics
The blush while a pretty pink is extremely tiny for the price of $39 USD. The eyeshadow duo was chalky and had very little pigment, the swatches were applied very heavily over a cream eyeshadow base while it was still moist. When applied to the eyes with the same technique, it barely showed up.
I also checked out the new Rouge Volupté Lipsticks which weren't my style either. The lightest one was #19 Frivolous Pink which looked like a neon powdery pink, extremely unflattering in my opinion. The others were very brown/plum.
Unless you're a die hard YSL fan, I'd suggest you save your $$$ for other items.
