Need help choosing the best shade for your skin tone? Explore our Prom Dress Shopping Guide for expert tips.
The easiest way to find out which shade or tone of blue will look best on you with your prom dress is to check out your jewelry collection.

If you have more silver jewelry, try light blue prom dresses or shades of sky blue in rich fabrics like glitter or sequins.
