I purchased OPI Number One Nemesis last year and only just got around to wearing it now! It's too bad that I waited so long as this golden olive foil (glitter? large shimmer?) is beautiful. I used three coats for opacity, but I would definitely layer it next time to preserve it. It's fairly similar to Chanel Graphite and I actually compared the two when I removed this mani, but failed to take photos. :(
I love the combination of olive and teal, so the deep teal of Sephora by OPI My Personal Serpent served as a great mani base. Almost a one-coater, I used two coats out of habit. I topped it with a coat of China Glaze Techno and I think my nails looked like a twinkling night sky.
I have to admit, I love this mani! The only downside is that SOPI MPS slightly stained my nails. I have to try it with a base coat before I purge it, though!
