I really like the layering on this outfit... or "version" of this outfit, as it's mostly the same pieces. That makes it really hard to name and categorize the costumes!
They're the same trousers, or an identical second pair—they have the same gold embellishment.
It turns out that that's not actually a brown shirt, thought I thought the same at first (otherwise it'd be another layer under the red tunic/vest). What looks like a shirt is actually just separate, probably detachable sleeves. They must attach past the edge of the vest, though, as the vest overlaps the sleeve. You can see the gap at her underarm where the white shirt shows through in this shot:
Thanks for lifting your arms like that, Georgie!
Also, in that shot, as in others, you can see the slit cut at the underside of the sleeve from above the elbow to midway down her forearm, where the white shirt is blousing out.
So now two vests, a pair of blue velvet trousers, a shirt, and
some detachable sleeves.
I might want to make this for myself... It all depends on Ramandu's Daughter's outfit.
