greeny-blue or blue dress is perfect. and a sweet heart top is good IF u have boobs which a cup B or higher

I'd definitely say a blue or sea green colored dress. And something with ruffles, it could make you look like a mermaid almost :)

This is a prom dress, i just put the link to show you what color i mean. Maybe you could get the design similar to this, but request that they make the dress greenish or blue:

That's a really fun theme by the way! I would love if my school did something like that!
