This season, the COS womenswear team reimagine the perennial shirt dress. Crafted from lightweight cotton poplin, it's cut to hit at the ankle and designed with a collarless neckline and an overlapping storm flap detail at the back that borrows from classic trench coats. It's detailed with an elasticated gathered back panel and tonal belt that allows you to personalize the shape. Relaxed fitButton closureSide slits Shell: 100% Cotton (excluding trims) / Machine wash Back length of size 6 is 48.15" / Model wears a size 6
