One Size, would fit up to standard 14 100% Silk Zip up center back First photos with pink tint on shoulder are accurate... I washed it (on a silk cycle) with a pink silk blouse and it had some color transfer. Did not change the shape or fit or any other color fastness. Included photos of before that, too, for reference. I think it looks better with the pink shoulder Purchased in 2021, worn less than 10 times. Incredibly small independent sustainable brand, doesn't produce many items per collection Open to offers
