Vintage 1930s bias cut silk slip. Peach silk crepe with tiny spaghetti straps and beautiful embroidery, cutwork and tiny pin tucks on the bodice. Scalloped stitching detail on the edges. Straps are not adjustable. Tiny tag reads Made in Italy. It is in very good condition, showing just a very faint mark and two small pin holes near the bottom. See last photo. 

No size tag. No maker's mark. The measurements listed below were taken while laying flat and doubled where appropriate. 

Shown on a US size 0 dress form with the bust clipped for shape. This is a very small size. Would best fit an XXS size US 0 to 2. Due to bias cut there is some slight stretch to the silk.

Waist - 32 inches (81.28 cm)
Hips - 36 inches (91.44 cm)
Length from top of strap to hem - 48 inches (121.92 cm)
