I ordered 3 because they were only £9 each and wasn't sure which to choose. And they're all good. To be fair, they're all identical in terms of style but different patterns. I'm a size 16 and they're really very flattering. here. Maybe not everyone's cup of tea, but they're lined and seem to be well made. Just saying.
I bought some of those last week - they're alright, quite basic, but the sizes are all over the place. The usual Damsel in a Dress stuff (non-Matalan) is massive I find - I'm a 12-14, and when I was after one of their coats, I couldn't get it small enough (they go down to an 8 and it still drowned me).
The ruched one in Matalan, I had to go down to a 10 - still a bit big. I'd go down two sizes in them all if ordering.
The fabric is a bit nasty but the real DiaD lines are too, so better to pay £9 than £100+ .
