The target was the last Merry Christmas (1860) of Queen Victoria. I am not sure what they were drinking back in the Victorian era for Christmas parties, but it sure would knock anyone out today. As soon as I started the session with the coordinates, I got extremely dizzy. Like freefalling style dizzy. Then laid eyes on a chubby lady wearing red and white gown of satin and permelin (turns out it was not permelin but probably lace) material.
While we don’t know what she was wearing in 1860 (we only have written excerpts of her diary from that day), a contemporary painting from 1860 portrays her wearing red and white on Christmas Eve.

Photographs of her from 1860 also show she was a bit chubbier in physique by then.

So the non verifiable data is reasonable.
