I own a fair few of these now in different prints and they are great for a smart-casual work look. Sometimes I'll throw a smart jacket over the top, sometimes I'll accessorise with a big belt or corset belt. The material is lightweight and has a little stretch to it but it holds well and doesn't appear like a stretch dress.
The back zip helps keep a great fit. The sleeves are the perfect length, especially for work.
The mock ups aren't great so if you want to sell these dresses you need to buy every single print you want to publicise.
