Hi Darling Girl!
You, my dear, are actually an elongated hourglass, which is when your bust and hips are the same size, and your waist is around 8-10 inches smaller. Not quite as much in and out variation as the true hourglass, but also a bit on the short-waisted side. Your best bet is buying separates, since you will be able to buy larger sizes to fit your shoulders and bust, and small sizes to fit your waist and hips.
With your broader shoulders you will look best in v-neck tops and dresses, button down blouses, classic blazers and cardigan type sweaters. Since you are a bit short-waisted stay away from high-waist trousers - stick with low-rise or mid-rise jeans and trousers. Do not give into the temptation of the super-low rise, however, as this style will flatten your rear view and make your shoulders look even broader.
A gorgeous look for you this winter would be a v-neck sweater dress that hits at the knee or a few inches above (show off those gorgeous legs!) paired with tights and knee-high boots.
