If you have mauvey lips, you need SS.
I agree with Liba.
My new favorite Nude is actualy SS. Oh my gawwwwd. I'm so grateful that T made it look bad. Her tendency to cake on products worked in my favor. I only do two swipes and it turns my mauvey pigmented lips into a MLBB shade. The texture is awesome too as it is very similar to Roitfeld's TT. It is moisturizing and it has a lot of slip. Some of the lustres can be drier, but this is definitely in the more moisturizing range. TT is more of a nude nude while SS is more a lighter version with some pearlized effect. Mind you, IMO it looks best when you do just two swipes, but this also means you have to reapply it more often. T must have done at least 10 swipes (who does that anyway?!?!) to get a frosty look - and the camera must have picked up this effect and even magnified it. As I am running low on TT, I'm glad I stocked up on SS.
