Ok ya'll, I need to find a swimsuit for Vi! Can I get some suggestions?

Here are the guidelines -

1. No Bikinis. I want a one piece or maybe a tankini.
2. Something Classic. Solid color, or polka dots, or stripes maybe.
3. If you find one with a matching swim cap, I will love you.
4. Affordable. Please don't show me $50 baby suits and make me want them.

Go!
