The Band Stays Level

The band around the top half of your body will rest fairly evenly against your back and front of your chest, but it will not be touching your shoulders. A correctly fitting bra will give you support and safety while being comfortable.

✓

The Cups Fit Smoothly

Check the edges of the cups to see if there are gaps, indentations or breast tissue. Cup shapes may vary slightly and may fit differently from one another even though they are labeled as the same size.

✓

The Straps Feel Comfortable

The straps need to stay in position and should not irritate or rub against your shoulders. The proper fit of the bra is determined by more than just the amount of tension in the belt.
