60s Gold Mini Dress - May be girls but may also fit very petite XS or junior size.
There is no fabric content tag, so I cannot say for sure what the material is, but it feels extremely thin and is non-stretchy.
No size tag: 13" shoulders, 16. 5" across underarm to underarm, 15" across the waist, 18" across at the hips /32" bust, 30" waist, 32" hips, 29" long - Model is 5'1" XS 31/24/34
Leave room for comfort, movement of arms.. micro mini length. Best for someone with small chest and slim shoulders.
Flaws: one sleeve seam is torn/frayed - see closeup photo. Underarms have perspiration marks as does inner neck. Not eye catching due to busy gold pattern. Gold shiny design has some mild wear at points of movement.

This item is sold from an excellent, highly rated vintage boutique.
