It's authentic all-right. I have the Morning rose nailpolish, and in fact it's not for sale, it's for internal use only. It's a gorgious color, it's a lovely bright pink with lots and lots of golden microglitters. I'm very happy with it
If Mimosa has the same amount of golden microglitters as this cutie I can assure you ladies.... you will find it to be irresistible, even though it is a bright yellow. At first I thought it would be similar to LA Sunrise, but after playing with the Morning Rose I'm convinced that Mimosa must be loaded with pretty gold microglitters. Otherwise.... I will be very-very-very dissapointed, LOL
