I have many tops with the peter pan collar. They're really cute and very feminine. I've seen quite a few interpretations of this in nail art and so I had to recreate it. I love the outcome!
I used a base coat of Rimmel Nail Rescue and then used hole reinforcers to create the half moon shape with two coats of W7 - Black. I then used a striping brush to add the 'collars' with Barry M - Matt White and a dotting tool to add the 'buttons' with Barry M - Gold Foil. All finished with a coat of Seche Vite.
