Definitely Sillabub - here's Bomba and Demeter from the same set of photos. They definitely look similar (mother/daughter headcanon? :P ) but Bomba has gloves not armwarmers. Bomba has more red and Sillabub more cream/tan colours but with the lighting it can be hard to see...

Also, I'm 99% sure the moment is from the beginning of the Ball, where Old Deut brings Victoria and Jemima/Sillabub forward to start the dance...
