Sinequanone Floral Spring/Summer dress

Beautiful dress for spring and summer. It's a brand from France. I used to cut labels on clothes, so I don't know size, but it fits S. Also would fit XS since it has ties at back. Very soft material. Worn only once. Under the pit it has barly visible pin size holes. See photos. Otherwise in perfect condition. Adjustable straps, 35" length.
