This is a great Fenn Wright & Manson summer work dress - it is black linen, with a cream contract trip at the waist (and a bow) and the hem. I loved it and wore it with the jacket in the last picture, which I am selling separately because the colour is not exactly the same as the trim, but I thought it looked nice together!
You can dress it up or down - mine is in decent fair condition, I cannot pretend I did not wear it on quite a few occasions, but it has a lot of wear still in it.
It's fully lined, which I think helps to minimise the linen creasing a bit and it zips down the side.
Mine is a size 12, but just to note, it is quite small - the armpit to armpit measurement is just under 44cm, so I think it is more like a 10. I consider myself a 12 now, and it would be tight on me.
