I started with two coats of OPI Pamplona Purple, a medium purple creme. It's one of the first OPIs I ever bought, and it's still one of my favourites. Once it had dried completely I placed a wavy French tip guide down the centre of each nail and painted over with OPI DS Extravagance. It's a stunning berry purple with a scattered holographic effect. I've shown you it before but my photos are, quite frankly, embarrassing, so I won't link to it! While Extravagance was still wet I whipped off the tape, and covered with top coat once it had dried.
