I am a size 12, biggish norks, slimmish waist, not brilliant legs (although kneelenght and high shoes is fine). Slightly matronly of upper arm. I need a dress or outfit for this 40th do. What I dont want is a Monsoon style v neck, sash waist, flared knee-lenght dress - yes that style suits me but I always feel very frumpy in it. Anyone?
