Harley is a pale grey shimmer. This photo was taken in the sun, the rest were taken in artifical light.
Barbie is a bit pinker and less peach in real life, it also has the beautiful shimmer that I love Zoya for.
Moxie is a raspberry creme and kind of the odd one out, my first thought was why didn't they do a mint green but after trying it out this is a perfect juicy berry shade.
Last but not least Jo. A wonderful powder blue with silver shimmer.
The Twist collection is up for sale now on Zoya.com. Zoya is also doing a polish exchange, I am not 100% sure when it ends, but I believe it is still going on right now. You can send them unloved polishes, empties, even minis and they will send you full size Zoya polishes. You have to pay shipping and I believe it is $3 per polish. You can go here for more details.
