How do you know if your bra isn't the right size?

If you can feel the back bra strap rising up, or if it molds into your skin making a 'dent', it isn't the right size. If the top of the breasts are spilling out over the cups, that is another indication. You might also experience straps that are too tight that they cut into your shoulder, lack of support, or a general uncomfortable feeling. Make notes on what makes you feel uncomfortable.

If the strap in the back is rising up toward your neck, instead of staying put just below your shoulder blades, you're wearing a bra size too big for you.
