There are so few choices for unitards nowadays that you have to go with what you need. You might need to have your unitard custom made. I prefer www.renaissancedancewear.com where you can pick your fabric.
But what's wrong with cotton/lycra unitards? I'll admit, since Capezio stopped making decent cotton/lycra unitards, the selection is limited. But Bal-Togs will custom make from a limited number of fabrics.
Nonshiny lycra and lycra/nylon material is limited, and if you're lucky to find the fabric, you have to have a seamstress or tailor make the unitard from scratch.
So what are you looking for?
