Vintage 60s Sleeveless Vacation Mini Dress with Embroidery - May be girls but may also fit petite XS with slim hips or junior size.
Zips down the front. There is no fabric content tag, so I cannot say for sure what the material is, but it feels like cotton and is non-stretchy.
No size tag: 17. 5" across underarm to underarm, 17. 5" across the waist, 17. 5" across at the hips /32" bust, 30" waist, 32" hips, 29. 5" long - Model is 5'1" XS 31/25/32
Leave room for comfort, movement, breathing..I would not recommend to someone taller than 5'1" due to micro mini length. Best for someone with slim hips!!
