Caroline, yes! :-) :-D
Caroline Williams is a London-based model from the 1980s. And she certainly has a lot of that city's stately elegance. All of her work from that decade was through three London modeling agencies.
She was represented by the Freddie's agency in 1982 and 1983, but she then moved to Take Two, which she mostly worked through for the rest of the decade . . . though she also modeled through the Nike Clark agency in 1989.
The color photo is from 1982; the beige-tinted black-and-white photo is from 1987.
