Antique retailer Vintage Late 1920s to Early 30s Long Sleeve Pinafore Apron Dress. Button Back Back Split Skirt. Large.

First glance one might think "nurse" but it's not a nurse uniform piece. Possibly a nanny or server's apron dress. Lightweight cotton linen (handkerchief linen like) with a V neck, breast pocket, and hip pocket. Long sleeves and buttons at the back of the neck and at the back of the waist, with an attached same fabric belt that buttons in the front. This one, like the pink, appeared to be crisp old stock, but in need of a soak, so laundered and air-dried.
Larger size, with bust measuring almost 21 inches across the front, 18 inch shoulders, and 18 inches across the waist. Again, it is not to be fitted, meant to be loose and is worn over garments, so best for a 30-33 waist.
Shown unclipped on a 32-24-33 form.
51 inches shoulder to hem.
