Last year MAC released some nail polishes with the Venomous Villains collection that were insanely popular! I did not manage to get any of them while but I heard that MAC’s Formidable was very similar to Orly’s Galaxy Girl, and MAC’s Mean and Green was similar to Orly’s Space Cadet.
You can see swatches of the MAC polishes and the mentioned Orly dupes here.
Here in the UK, we have our own little gems, some dupes for the MAC and Orly colours hidden away in Accesorize! They are only £4 a bottle but they look so similar that it is almost impossible to tell the difference.
I picked up one recently, Shade 38 Illusion Aztec. The main colour of the polish seems to be a deep moss green with a purplish red duo chrome and rose gold shimmer. It is beautiful!
The polishes are really good quality, the formula is excellent and it goes on smoothly without streaking. You can achieve best results from 3 coats. The brush, while being a little short, is a great size and shape.
The range of nail polishes can be found online at Accesorize's website. From what I’ve seen Illusion Bronze is the dupe for MAC’s Bad Fairy, and Illusion Purple Dream is the Dupe for MAC’s Formidable, so I may be getting those soon!
