From The Mod House, this is described as an Overlap short sleeve blouse, we say its more like a jacket. Sheeny blue, with a black and silver trim button, inner popper fastening to the opposite side, short sleeve with pleated darts for fullness. Size is M - to fit approx size 10. Waistband measures approx 30". Swap item. NB. New with tags (original price around GB 25.00) but NOT perfect - a few very minor pull lines to the left hand sleeve, not very noticeable.
