Cobalt blue is one of the best traditional bright evening dress colors. It's such a strong, vibrant color to make a bold fashion statement.

It's often just too strong for the day but fully glam at night. Every girl should wear a cobalt blue dress at least once in her life.

This evening dress looks nice but it needs some contrasting color or fabric. The color is so overpowering it could use some black or even navy blue accessories to tone it down.

There is a little fancy trim at the neckline of this evening fashion by L'Wren Scott that looks so refined.
