I've only tried it on, I've never actually worn it out. The size is L, but I think it's quite small. The back is elastic, but it's made of velour material so it doesn't stretch much. The suspenders are integrated and cannot be removed. Pair it with a blouse for a ladylike fashion look (*^-^*) Skirt: 50cm, including suspenders: 85cm This is what I measured when laid flat, so please use it as a reference. Pattern... Solid Season... Autumn/Winter Color... Black
