I bought their white color: I need a tan, at the recommendation of Ella+Mila as an undercoat for the lighter shades of polish I bought along with it., like Creamsicle. Putting down a coat of white before using the lighter colors makes the color more opaque. Take your time and let each coat dry thoroughly before applying the next coat. I only need 2 coats of color. If I were better at applying it, I bet I’d only need one coat of color. Use their clear top coat to seal it. Works great! Out of alllll the colors I’ve purchased from Ella+Mila, I believe this Creamsicle will always be my favorite!!
