Where to get shiny metallic zentai?

I've been thinking about getting a shiny metallic zentai suit finally... Not just a simple zentai suit, but instead one that makes me look like a zentai mermaid/merman. But I have a couple of problems: 1. Which size should I go for? I'm usually around sizes S or M with regular zentai (depending on seller)... 2. Where should I get that suit? Any recommendations are welcome! 3. How do I store it properly? Plan to move out of my current place in the near future, if it works out well... Any help is greatly appreciated! :)

The metallics are more stiff and less stretchy, so sizing is more important. Need to hand wash but even limit that as the sheen washes and wears off. But it is a great look if properly secured.
