I'm a similar shape. Apparently, V necks are good. No frills, ruffles, etc. around the neckline. I've got dresses which are similar to those on that link you've put on....they don't flatter me at all.
I generally like to wear bootcut trousers, ankle boots with a heel, and a blouse/top with a V neck, but which is long enough to cover my belly. I like patterns, never stripes.
I also have decent legs, so I wear dresses that are knee-length, with either court shoes or knee-length boots (both with decent sized heels).
I always buy well-fitting bras (I'm a G cup) with wires of course.
Under dresses, I wear a Gok Wan bodyshaper all-in-one thing.
I like to wear colour. Never black on top, as it makes me look old and pasty-faced. Simply Be and Yours Clothing are good.
