Creme Cup is a nice, blue-pink lipstick that feels creamy but doesn't go on quite as creamy on the lips. If you have any lip imperfections (like lip wrinkles or patchiness) Creme Cup will emphasize it. Otherwise this is an excellent lipstick that creates that perfect, glossy pink lip but looks best with a semi-sheer or sheer lip gloss. I usually pair Creme Cup with with a milky pink lip gloss for perfect lips. :D
Nude for those who look 'dead' in canon nudes. It is definitely pink, and described as "light blue pink" by MAC. On me it looks very neutral--muted dusty pink, a bit lighter then my natural lip color. Looks great with dark eye-makeup, or everyday 'natural' looks.
Formula-wise it is opaque, not drying, doesn't bleed or settle into lines, wears well (~3-4 hours) and fades w/o drama leaving my lips in presentable condition. A staple in my makeup bag, a must have pinkish nude--very flattering on fair skin (can look milky w/ tan).
I find Creme Cup weird. It's a nice colour, but the creamsheen formula is weird on me, and seems to be patchy and shows dry patches. I also don't find the formula on this one to be as good as say Amplified finishes, being not opaque enough for my liking. Bit of a bummer, because its a lovely everyday colour.
