Very thin. No lining. 100% cotton. It's cute worn loosely as a large dress or as a tunic, so I think you can use it for a long time. It has been used, but there are no stains or pills. The cuffs used to have elastic to gather them, but the elastic has stretched out and no longer gathers. Measured flat, approximately 57cm from shoulder to hem, and approximately 37cm across the chest (underarm to underarm).
