NWT Blanc du Nil white sleeveless 100% cotton midi dress

NWT Blanc de Nil white sleeveless 100% cotton midi dress with v-neck and slight lettuce/ruffle hem. Gorgeous quality and never worn. It was a gift and just doesn’t fit me. The lay flat bust measurement is 20” The lay flat waist measurement is 20” It flares out slightly from there. Probably hits midi or ankle length on average height women. Marked size 46 (probably European), but I would maybe equate it to a US size 10-12. Pet and smoke free home.
