For those of you who wanted me to report back...
it has arrived.
I am pleasantly surprised. But it's too small. I ordered an 8 but it will only just fasten. The shoulders are fine so I am anticipating the 10 being too big on the shoulders- but will exchange and see.
The pale blue colour looks - dare I say it- chic. (I am goldy-blonde and pale-ish).
My only reservation is whether i will wear it that often. I have just bought the taupe trench coat from Mint Velvet as a spring/summer coat.
