I have just bought two from Next and thought I'd write a little recommendation to anyone who was after one!
I bought this
navy
which I am keeping-it's lovely. Just above the knee (I'm 5 3) so I'm glad I didn't get the petite! Sizing is generous, so I sized down which fits perfectly. It's very flattering-lovely sleeves and no need to wear anything underneath. It also has POCKETS which is very exciting!
I also bought this
yellow
which I really love. Again-I sized down. It's knee length and very pretty (though no pockets) but it's rather see-through :( I could wear a vest underneath it, but that sort of defeats the object of a summery dress, so sadly it is going back.
HTH someone looking for something for the summer!
