There are so many reasons to love the Billboard Music Awards. The music, the performances, the chance to validate ourselves for singing that crazy-catchy, crazy-annoying song (hey, it won a Billboard Music Award!). And as with any award show, it's a chance to check out some pretty amazing hair and makeup looks.

And the Billboard Music Awards are especially fun because they happen right on the cusp of spring and summer, which means they give us some of the most refreshing and stylish picks of the season. Sure, Taylor Swift and Kelly Rowland owned the blue carpet with stunning head-to-toe looks at this year's show. But there were other swoon-worthy celebrities that made us do some serious double takes.

Ready to see who we deemed gorgeous enough to be on the "best" list?
