I don’t imagine this is the worst ever description in a novel of a woman’s walk, but it’ll do for now:
“You walk with a headlong rush, there is an electric energy in you, a rhythm that gushes from your mouth in a broken Bronx college-girl jargon, that tilts your narrow hips, that drives the blossoming female bulge of you, full and achingly free beneath the black skirt."
It’s from Evan Hunter’s Buddwing, a novel that in general I’m inclined to like, not least because it has a fair amount of walking in it, but even so I mean really.
Others must have liked the book too. It was made into a film as Mister Buddwing, starring James Garner (who hated the end result), with Jean Simmons, Suzanne Pleshette, Angela Lansbury and Katherine Ross. The description above describes a character named Janet, played by Katharine Ross.
It has not been easy to find a good picture of Katherine Ross walking. Here she is in Mister Buddwing with Garner:
and here she is shopping in Malibu (during Covid, I imagine) with her husband Sam Elliott:
And here she is some time ago by herself. I’ll leave you to decide about the blossoming female bulge.
