The fit is a semi fitted fit according to our sizing chart. If you fit towards the end of the measurement I would order up a size to insure proper fit after your first wash. If you see our size and fit tab of this box you can see how it fits a human form based on the measurements in our chart. The actual bust measurement of the fabric (not of what it will fit) is the same as the first measurement in the range for bust measurement. For example the small is 34".
