Reformation Black & White Polka Dot High Collar Sheath Dress Size Medium

Reformation Black & White Polka Dot High Collar Sheath Dress Size Medium Tag says medium, but works for a small (my size) with a looser fit too High collar with two hooks at the nape of neck to create a keyhole back Large armholes for a little side boob action No defined waist, flares out from chest Super cute and academia style Excellent condition with one flaw; there is a brown line on the back of the dress from a marker (see pics) Approximate measurements Armpit to armpit: 21" Shoulder to hem: 32.25"
