Niva the dress is beautiful, but I find the quality of AA items very hit and miss.
I would never risk tumble drying an AA item as they are prone to both stretching and shrinking.
Last summer I purchased two tops for myself and was impressed so I ordered two tops for Ben for Fathers Day and I had to return them both. The first tops material was so sheer it was indecent (loose fit) and the second top, a horizontally striped grey and cream v neck, arrived with haphazard diagonal stripes.
I have also found loose threads on some of the items and the sizing is very inconsistent, however, I would still order from AA for their colour selection but I would expect to have to return a large number of the items.
