I bought this last year. I bought it for my child's swimming class, but they only wore it twice because of the rain and heatstroke warnings. It's a unisex S size, and a parent (average build, size M) tried it on and it fits without being too tight. Suitable for the pool, outdoor activities, and gardening. Size S Flat measurements: Bust 43cm, Sleeve Length 76cm, Length 61cm 95% Polyester, 5% Polyurethane
