When I was deciding on whether to get Essence Ballerina's Charm, I was a little hesitant as I recalled Orly You're Blushing is a dusty purple as well and was wondering if they were too close to have both of them.
I took a chance and I'm glad to conclude that they are not dupes. Ballerina's Charm (left) is lighter and cooler, with tiny silver shimmers. While You're Blushing (right) is darker, slightly taupe-ish and no shimmers.
Hope to have helped if you had the same question in your head ;)
Thanks for viewing!
