Definitely Cool Heat - I can't wait until summer, so I can continue enjoying it. Solar White makes me weak in the knees. And I loved Gulf Stream, and want to play more with it.
Right now, I'm still in love with my CoC Shadowy Lady Quad, and Lightly Ripe Lipstick. I'm also loving my cool eye palette from the holiday collection, and surprised by how much I love the pink side!
