Measure your doll for proper fitting Measurements- One Piece Top to bottom 14" , Shoulder to Shoulder - 6", Armpit to Armpit - 8"
Half Slip- 10" Long and will pull together at least to 5" or less and be as big as need for any antique doll.
Beautiful pieces are made of a woven cotton looking material? The one piece slip buttons on both shoulders and has a flap in the crotch that turns up and buttons. I don't see any staining but there could be a light spot I've missed.
The matching drawstring half slip has several pin tucks and what looks like tatting along the bottom and through the middle. This piece is also clean and free of any noticeable staining.
