I have worn it. Here is what I would tell you.
Real sizing notes on the Zyia Active pieces I live in, written to the women in my community after wearing them. Not a size chart.

I have said it in a hundred messages. Now it lives here.
I'm Jessica Perez, a Zyia Active Independent Representative. I wear this line every day, I answer sizing questions every week, and the same answers kept coming up. So I wrote them down in one place, with my own photos, so you can size right without the guessing.
If your piece is not here yet, message me in my group and I will tell you what I know.
What actually fits, piece by piece
My call on every piece, and the notes it came from. Three to start; 23 in the library.
Size right the first time
The whole library on one page, the version I would hand you in a fitting room. Leave your email and I will send it, and write again only when I learn a new fit truth.
Opt-in only. One email with the guide, then only when there is something worth saying. Leave any time.
