I did one thick of white then two coats of Bootie Babe Electric Lemon. Neon polishes pop over white and show their true brightness. Then I used a dotting tool and Sally Girl Way Cool for the polka dots. I adore pink and yellow together, especially bright shades of both.
Bootie Babe retails for $4 on their website. In June, they will start selling their polish in bigger bottles (15mL versus their current 9mL). The caps will also be taller and easier to handle, though I had no problem with the current caps. For more info, check out their Facebook page. Sally Girl retail for $1 at Sally Beauty Supply.
