I am a fan of Flannels, their ranges each season are so different from other stores and their own promotional photography and choice of models is spot on. They have some great discounts too on individual items, check back to the web site regularly (they now have a new very fast web site) and use the search facility (bottom right) to look at designers you love.
I have jotted notes in the past about Flannels great investment pieces and offers:
Prada Sable Dress reduced from £625 to £120.
Hugo Boss Animal Print Silk Scarf reduced from £115 to £60
ASH Tan Ankle Cuff Sandals reduced from £165 to £80
The extra 20% off makes the pieces even better value.
