I’m no expert on judging eras but I think it could be from the 30s to 50s. The fabric is still good and sturdy and wearable. However, a couple of flaws at the top of each pocket needs to be repaired as shown in the photos. Metal zipper and hook and eye closure. Measurements lying flat are- Ptp 18 in.,- shoulder 14.25 in.,- waist 16 in.,- hip 21 in.,- length 40 in.,- sleeve 6 in. Gently washed and ironed and ready to wear. Thanks for taking a look!
