I recently purchased Style Curve lipstick which came out with the Stylishly Yours collection and I should have passed on it!!! On the MAC site it looks so bold and bright and while it's pretty, I have a very similar color.... Violetta!!!
While Style Curve is a creamsheen and Violetta is an amplified cream, they look EXACT in color to me!! So if you already have Violetta, I suggest leaving Style Curve alone, but that's just me.
