If you’ve read The Moonlight Mistress, you know that Lucilla, rather than a corset or brassiere, wears a bust bodice. Below, a picture of a bust bodice.
Some models reached as low as the waist, and some were worn in addition to corsets. They were popular through the 1920s.
About Victoria Janssen
Victoria Janssen [she, her] currently writes cozy space opera for
Kalikoi. The novella series A Place of Refuge begins with
Finding Refuge:
Telepathic warrior Talia Avi, genius engineer Miki Boudreaux, and augmented soldier Faigin Balfour fought the fascist Federated Colonies for ten years, following the charismatic dissenter Jon Churchill. Then Jon disappeared, Talia was thought dead, and Miki and Faigin struggled to take Jon’s place and stay alive. When the FC is unexpectedly upended, Talia is reunited with her friends and they are given sanctuary on the enigmatic planet Refuge. The trio of former guerillas strive to recover from lifetimes of trauma, build new lives on a planet with endless horizons, and forge tender new connections with each other.
Is that like a bra? It doesn't look very supportive.
It has boning and fits snugly – it's sort of an intermediate step between the corset and the brassiere.
