How visible was your bra under the leotard? Was it just the outline, or could you see colors really well (would nude under white be a problem?)

You can see undergarments thru the leotard but from experience if you are wearing nude underneath, you would eb less likely to see it. My neice has a pink and lavender one and wears white under it. You can see the garments so she wears a waist wrap as well. I would say to answer the question, you would be able to see the entire undergarment and not just an outline (especially with a lighter color leotard). Teresa

What material is the leotard made of?

The body is 90%NYLON 10% Spandex. There's a lining in the crotch that is 90%polyester 10%spandex

Where is an accurate size chart? xs, s, m...
