(Quoted text is from the Wikipedia "Gibson girl" article.)
The Gibson Girl was tall, slender yet with ample bosom, hips and bottom in the S-curve torso shape achieved by wearing a swan-bill corset; she was fine-featured, and achingly beautiful.OK, that last bit is subjective, and I definitely need a bustle to be ample in some respects, but I think we're getting there, comparing this photo
with this photo of Camille Clifford, who Wikipedia says was probably "the most famous Gibson girl":
Hair, OTOH, is proving more difficult. There are "updos" to be found in SL, but so far I've found nothing that is anywhere near the "big hair" of the Gibson girl. I dare say that Victorian hair is an unfilled niche in Caledon.
