I think I get way more mileage out of Flash of Flesh,.. Sometimes it looks pink, sometimes peach,. always shimmery and gets compliments day or night,.. I have a backup of this one and agree that when I finally go through that backup I will have a fit. It is definitely one of those that I keep in my purse at all times,..
Gitane is beautiful and a lovely deep red with an orangey chocolate tinge. Its a bit harder to wear as it is dark and if it "travels" out of the lip line it is very obvious. A great addition to anyones collection, but I don't really reach for it that often.
