Exposed zip mini dress

Francesca's // Myan label: Dark purple/eggplant patterned ivory shift/mini dress with a contrasting grosgrain-trimmed back zip. 3/4 length sleeves have elastic detail at the bottoms. Unlined, worn twice. Cute with flip flops, heels, or leggings and boots! Tag says medium but in my opinion it's on the smaller side of Medium.
