I'm not entirely about this manicure BUT the glitter accent nail is bomb!
For this manicure:
Apply one coat of your preferred base coat. I used OPI's Base coat.
Apply two coats Etude House's PP079 - Purple.
With a X patter nail vinyl from Twinkled T, apply to the middle finger nail and using Skinfood's white polish and a sponge, sponge over the vinyl. Wait a few seconds and remove the vinyl.
Using Etude House's GR073 - a mix of turquoise, yellow, purple and silver glitters. Apply to the ring finger nail.
Seal everything with a top coat. I used a top coat from Skinfood
