I had a similar Ossie Clark in the seventies when I lived in London - this one was bought in California and is just amazing. See photo of the panels of satin on the gored crepe skirt and jacket. It is worn on a size 10 model and it fitted really well. Could fit a bigger bust- see details on the jacket at bust - sleeves and cuffs. Rare to find such a pristine outfit from the 70’s.
Model is tall and 34”bust and a size 10.
The shirt can be worn inside or as a jacket
Please note: missing button on front - reduced now
