Cobalt blue is just a pretty color for the spring and summer! Since the color is so bright, my preference is usually to wear them with an all white or all black palette. If I am not going to work, and want to try something trendy, i'll pair it with florals, hot pink, and/or neon yellow.
I love the sleekness of this outfit. It's so classy yet colorful and fun at the same time.
