I know I made repetition of posting topshop dresses, navy, velvet stuff recently but I just can't stop looking at lovely velvet dresses. Here are some with floaty loose fit which brings out the tenderness of dark coloured fabric.
PETITE Berry Purple Peter Pan Collar Velvet Dress from Miss Selfridge
A really nice one from ebay, it's a mini dress from the 90s in crushed velvet blue with black ribbon so pretty.
