(I presume there’s some following me, or that followers might know someone) 

I’m looking for the technical term (for novel research) for a kind of upturned, large lace collar on women’s clothing. The examples here are from BBC’s The Musketeers, which I know isn’t anywhere near accurate, but even allowing for artistic licence there must be some truth to them.

(and even if they aren’t, this is for a fantasy novel so I can have them if I want to)

The closest term I’ve been able to find is rebato, or possibly a ruff or collar with a supportasse. In my manuscript, I’ve described one character’s clothing thus:

She had not taken a mantle; it had seemed a waste to wear it. Most of her clothes were still on the northern shore of the sea. They would remain there, pass into the ownership of whoever replaced her. To her trial she would wear this brocade dress with its silver thread, this blue silk holding back the dark curls of her hair, this lace collar fanned about her head, symbols of the Gods framing her face.
