After browsing a bit I found this lovely dress on Asos, and immediately knew that's what I'm going to do in my design.
At first I though that maybe I would cut stars shapes off dried nail polish on a plastic bag, but after few failed attempts, decided to stamp the stars.
The blue polish is Zoya - Natty, And the colors that I used for stamping are: Konad white stamping polish, Moyou black stamping polish, KIKO 619 & KIKO 628. The start are from Cheeky CH5 plate.
I topped everything with Essie - Good to go rapid dry top coat.
