Skyline Blue no 15 and  Dusty Turquoise no 13 are great colours if you want to follow the lates trend.
Blue pastel is seen both on and off the runway. Models are wearing it together with edgy clutches, a white T, ripped jeans
and a cute pair of black pumps. A pair of converse and jeans will also match perfectly with your blue nails.
If you want to go a bit darker, go Midnight Blue no 14,
