Lol. Sad thing is, I don't keep track of water-to-dye ratios, so once I finally get to dyeing my real fabric, I just kind of guesstimate. This is what I ended up with, after about 12 hours of dyeing, washing, drying...

The shirt fabric (hemp cotton jersey knit) came out great! Dharma no longer sells the natural color, so I had to start with the white. I used a
very diluted dyebath with RIT Taupe.
I think the headwrap fabric (heavy gauze from JoAnn / Cosplay by Yaya Han) is all right, though I could go darker on it. I'll probably keep it as is and just weather it a ton. I threw it into the same diluted Taupe.
The pants fabric is stone wash crepe de chine from Dharma. I used a 50/50 mix of RIT Taupe and Pearl Grey. I mostly like the color but think I might try adding a bit of green to them.
The wrap dress fabric seems too grey to me, but it matches a lot of reference photos, and I know it'll photograph lighter, anyway. This is the JoAnn crinkle cotton, but I'm not positive which color it is, as it's been in my stash for a while - it's darker than their current Papyrus but lighter than the Natural. I threw it into diluted Taupe, but after it dried thought it wasn't grey enough, so I threw it into the leftover pants dyebath (Taupe + Pearl Grey) very briefly.
Interestingly, I did try using some of Dharma's reactive dyes, and 50/50 Safari Grey + Ecru is super close in color to RIT Taupe. Which is why I ended up using RIT instead of all the fancy dyes I'd just purchased.
Now it's time to get to sewing! I'm planning on using the McCall's Rey pattern as a base and modding it for accuracy.
UPDATE:
Added a bit of RIT Apple Green to the pants fabric. They're a bit light, which should be fixed with weathering, but I'm happy with the color!
