Here are the measirement we use in the Dress Calculator, so you can also evaluate for yourself.
Take your body measure firmly on the body, and enter in the table. All measurements in the table are in cm. and note that it is body measurements and not dress measurements. If the dresses are large or small in size, it is specified in the product description itself. Remember that a wide model can be large in size if you do not want a loose dress. Then go down a size of wide model.
