I absolutely love shopping for baby and kid swimwear. The ruffly skirts, the sparkles, and especially the rainbow prints, remind me of my own childhood and those magical summer days filled with sprinklers, slip n' slides, and, of course, some epic jumps off the diving board. If you're feeling those nostalgic summer vibes too, we've rounded up 10 rainbow swimsuits for kids under $20 that are guaranteed to make your little one feel all of that summer magic.

When I was little, my friends and I would literally spend hours in the pool flipping our hair back like Ariel from The Little Mermaid and laughing until our bellies hurt. It never got old and full disclosure, I still think it's fun. That's why when I see my preschool-aged daughter splashing around with all of her little buddies — each of them wearing the cutest little swimsuits I have ever seen —  I can't help but smile. I know that she's living the dream. In fact, just the other day she spontaneously declared, "This is the time of my life day!" It really doesn't get better than that!

To jumpstart all of that magic, here are 10 affordable swimsuits that are so very rainbow-licious. Plus, since it's already mid-summer, a lot of the items are majorly on sale. There's no better time to stock up on swimwear than now.
