I am not sure on this, so seek the S&B wisdom! I am 5ft 3 with 32k norks, and nearly always wear low, wide scoop necks which look more flattering on me. In the winter I then have to wear scarfs to cover up expanse of skin as I am a chilly mortal.
I have just ordered this dress in Sapphire from Boden, which I really like. It is very flattering on my lower half, makes my stomach look flat. I love the petrol blue colour (not as bright as the photo) and feel of the fabric. The one thing I am not keen on is the high neck, which gives me a well upholstered look! I wonder if a long necklace will give me a sort of deep V in the front and break up the large expanse of fabric. And if so, what sort and where do I find a necklace to go with it?
I am 45 and an hourglass shape, only wear skirts and dresses (just saying, as I know if you are younger and wear lovely skinny jeans, it will probably scream frumpy).
