Hips: 40" to 46" about
Waist to bottom hem: 23"

Please note: These are vintage, preworn and/or preloved items. I do my utmost best to list any issues, but signs of wear should be expected, and there are occasionally small things I won't deem worthy of note. Please feel free to send me a missive with any questions. I'm truly happy to help in any way possible and I'm always up for a chat. Any accessories shown, including crinolines, are for display only, not included unless otherwise stated.
