If you like wrap dresses (or that sort of shape anyway) check out Matalan who have just launched a range of D in a D dresses.
I've ordered the Opus one in the purple and in the [[http://www.matalan.co.uk/womens/brands/d-by-damsel-in-a-dress-dresses/s2580395/d-by-damsel-opus-ity-dress blue]]
At £80 cheaper I can't believe they're the same quality and fabric as the ones on the D in a D site but they look very similar.
I've also ordered a couple of patterned ones too. I got 20% off with code AFF320 so am feeling chuffed, fingers crossed I'll feel the same when the dresses arrive 
I'll report back.
