Rosie is a mock neck midi dress with split batwing sleeves and a relaxed straight cut. The gathered mock neckline is what sets it apart from an ordinary shift: it adds texture at the top of the dress and gives you somewhere for a simple gold chain to sit. Between the neckline and the open shoulder split, the dress has enough going on that you can wear it flat with sandals and still look finished.

Soft ruching gathers at the mock neck to create the dress's focal point. The batwing sleeves are cut with an open split at the shoulder, a small cutout effect that changes how the dress moves and photographs. Below that, the silhouette runs straight and unstructured, draping over the body rather than clinging, and the hem is curved and slightly asymmetric so the base looks shaped rather than simply cut off. Sizes run S to 2XL.

Rosie comes in five options: Pink, Blue, White, White Flowers and Beige Pattern, so you can take the plain shades for everyday or a print for occasions. Wear it with flat sandals in summer, with boots and a jacket in autumn. Wash cool, keep it out of the tumble dryer, and hang the dress to dry so the sleeves and hem keep their line. Free US shipping and our 30-day money-back guarantee included.
