Allure magazine, in it's June 2012 issue, recommended the following four shades, which go well with any summer sandal:
1. Red-Orange (Essie's Bazooka)
2. Shimmering Aqua
3. Electric Purple
On a separate note, advise clients to stay away from these three polishes:
1. Pale yellow: It can make nails look stained.
2. Mauve: If it's too similar to a client's skin tone, it can make them look corpse-like, manicurist Jin Soon Choi told Allure. Recommend a shade of pink or purple with higher contrast.
3. Just Glitter: Allure says it's like borrowing a teenager's miniskirt. It doesn't make you look any younger, but it will look cheesy.
