Help ! I am 6ft tall and size 16 and knew I would struggle to find a dress. I have seen one I like in Hobbs (Astraea blue) but it falls to about an inch above the knee. Do you think this is ok ? Also it is mainly the colour of the men's navy suits so wonder if this would look odd. The wedding is in a farm/barn type setting and my daughter does like it. Any advice much appreciated as slowly going mad with indecision !!
