Dress Features and Styling
The midi dress features side panels at the hips that create a flattering fit-and-flare silhouette. Seam detailing and a dropped waist nod to a vintage pinafore aesthetic, while the contemporary zip-up round neck adds a modern edge. Style it with a crisp white baby tee and chunky leather slides for a casual look, or dress it up with a lightweight cream blazer and strappy block heels.
Shopper Reviews
The dress has a solid 4.6-star rating from shoppers. One reviewer said: "Perfect dress. It fits a treat, really comfortable and very flattering." Another added: "Fabulous fitted style. Casual/smart. Wore it to a baby shower. It will look great for festivals/concerts on its own or styled with a suede jacket." However, one customer noted: "This dress looks lovely on, but I had to get a replacement as a couple of the seams showed a weakness, which hopefully was a one-off." Another fan said: "Nice Denim Midi dress. I went for the petite length, and at 5ft, it comes to about two inches above my ankle, which is fine for me. Great with sandals or a layered t-shirt, etc., and boots when autumn comes. Very versatile."
