This NOTD netted a lot of compliments from my coworkers. I think there's something about gradients, especially sparkly gradients, that just really grabs people's attention- one colleague referred to this mani as 'Cinderella nails'.
I started with a base of Chic Show Biz (410) which is actually a fantastic off-white color, I've been using it as a base for almost every gradient I've done recently. It's nearly a one coater, but it's softer than a stark white so if a little peeks through it's not so obvious. It's also got a subtle shimmer. I strongly recommend buying it as a nail art/gradient base, it's a staple for me.
The other polishes I used were:
Chic sugar finish collection 04 (pink)
Chic Sinful Tops 709 Love & Hate (purple)
Chic Sinful Tops 711 Naughty Blue (pale blue)
Ga-de 55 Blue Sugar
Konad blue stamping polish
Initially I wasn't planning to use the Ga-de blue, but the lighter blue I used turned out to be too sheer to be effective in sponging, so I added a little extra at the end.
