Full Tilt (Tilly's) lavender spaghetti strap dress

Only worn once and washed. I think it shrunk a little because, although it is an XS, it almost fits like a bodycon dress. There are a few darkish stains from the wash close to the bottom hem of the dress (as seen in pictures) about 14.5 in (36.8 cm) across bust about 27 in (68.6 cm) from top of dress to bottom
