A quick comparison between OPI Tease-y Does It and China Glaze Midtown Magic. They’re pretty close, but not dupes… more like nail polish cousins.
Tease-y Does It is from OPI’s Burlesque Collection and has a deep purple/brown base with red/gold shimmer. The shimmer seems to also flash green from time to time, but it’s not terribly obvious. The formula is opaque and smooth in two coats.
Midtown Magic is from China Glaze’s Fall 2011 Metro Collection. It has a very dark burgundy/brown base with gold/bronze shimmer and the application was similar to Tease-y Does It… smooth and opaque in two coats.
