Beautiful dress from indie brand Portrait of a Girl (I think no longer operational?). The colour is incredible as is the cut.
It has a full skirt, with double layered cotton. The waist is elasticated.
It's a US6 - a great fit for a UK10. Sits on the knee (based on a height of 5'7"). I would say that it is better suited to shorter women as the waist sits quite high, so if you're tall your body is likely to be too long for the dress. I would say a good fit on those 5'5" or shorter.
In excellent condition.
