Long, sleeveless, halterneck dress in a patterned weave with ties that fasten at the back of the neck. Pleated bodice with an open section at the front and smocking at the back, a seam at the waist and a softly draping, gently flared skirt. Lined.
Tag size XL suggested by H&M for UK 20-22 but might be suitable for UK 18 too as it is pretty adjustable
