From the picture, I thought this gown would be more of an mauve color, but it's a pretty periwinkle blue.
It's a lovely style, and looks great with or without my Museum Replicas farthingale. I prefer it with the farthingale to keep the hem from touching the floor.
I'm 5'9" with a longer torso, about 190 lbs. I ordered a large. I was worried the waist and skirt might be too short, but both are just fine. I was able to slip the laced gown over my head, then tighten it with the waist ties, no handmaiden needed.
The gown is 100% polyester with a 100% cotton lining. The cotton lining isn't ideal to slide over my cotton farthingale, but it wasn't terrible. Might make a silk slip to go between the two for maximum drape.
Love it, love it, love it!
