How to Determine Your Dress Size??? 1 Measure your bust. You'll need to measure the fullest part of your bust (NOT bra size) to get the proper measurement . 2 Measure your waist. Bend to one side and find your waist's natural crease. At the crease, measure around your waist, making sure that the measuring tape is a bit loose. You can also find your natural waist by measuring 2 inches up from your belly button. 3 Measure your hips. Stand with your feet together. Measure around the fullest part of your hips and rear. 4 Look at our size chart. Keep in mind that size charts tend to be different for different styles, you can use the size chart as a basic guide. Always choose the larger size if your measurements come between two sizes. Avoid the dress size generators, as they tend to give you the wrong sizes.
