OPI Design Series Signature is a beautiful, raspberry-colored holographic polish with undertones of mandarin orange, lavender, and electric blue. It's an insanely beautiful color. It pretty much leaves me in a sub-verbal state, staring at my hands and saying things that sound like, "mmmmpretttty." There might be some inadvertent drooling. Anyway, it's standard OPI: good formula, two coats. Before you scroll down to look at my photos and then lose the power of speech over the coolness of this polish, don't forget to enter my giveway!
