There’s a reason we call cobalt blue "royal" or "king’s blue." 

It exudes crisp sophistication and authority. Like peering into the ocean on a sunny day, it holds an air of mystery in its richly pigmented depths. 

Commonly associated with stability and calmness, cobalt blue is an excellent color to incorporate into your big day. It’s a grand yet tranquil accent color for your wedding dress, which makes it the ideal color for your bridal party to wear.

We’ve rounded up a collection of gorgeous blue bridesmaid dresses in various styles and are excited to share them here. 

Be warned: if you weren’t sure about cobalt bridesmaid dresses before, you will be after seeing what we have in store.
