Serena downloaded some magazine scans onto her iPad and showed me a nail design from there. The only modifications I made were the colours (as picked out by Serena) and switching from disco balls to white polka dots. The result:
I used Gelish Desert Sands for the base and for the tips, I used Angel Pro Gelly Polish in #14 (light grey), #25 (blue), #12 (light purple), #13 (coral) and #39 (light pink). For the polka dots, I used #47. the ribbons were done in #2 (pale yellow) and outlined with a custom mix of #29 (black) and #31 (brown). Whew!
