Powder blue is a cool colour by nature, so it works well with accessories in other cool tones. You can team it up with diamond earrings and a clutch and a pair of cones or peep-toe shoes in silver. Accessories in white, cream or beige are also great choices. If a stunning contrast is what you are looking for, you can’t go wrong with black or dark shades of blue. A pair of oversized sunglasses and a sun hat will complete your summer look quite effortlessly.
