A Lingerie dress?

But thats what it's called. I think because of all the tiny pleats down the front and back of the bodice. It flares out at hip then then tucks up for the skirt which is also pleated around and so far down. Little ribbon roses decorate the neck and skirt. A little lace trims the sleeves and skirt.

 I think this one was intended for play as well as other times. It's a darling dress, and another different style for this era.
