If you cannot give up black color like me, then, you will adore these black prom dresses. I feel very comfortable, cool and self-confident in black pieces, so I'm sure you will, too! Black may be a very traditional color, but it always shows its difference everywhere. By the way, among the dresses above, my favorite is the bottom right one.
If you want to be pure and feel like a naive princess, you can choose simple or less sophisticated long dresses with pastel colors. It can be strapless, with straps or short sleeves. You can choose anything you wish.
