Full Figure Bras
By far, the most common error among full-figured women is buying a bra with cups that are too small and then compensating by going up to a band size that is too big for them. This mistake is understandable since many bra styles typically don't come in larger cup sizes. Find out what your measurements are, and only buy bras that are made specifically for your measurements.
A second problem is denial. Our culture is focused on small body shapes so this adds tremendous pressure and challenge to the full-figured woman's psyche. You need to wear a bra that fits your body. A smaller cup size isn't going to make your breasts any smaller, but a properly fitted bra will at least be comfortable and better for your physical health.
Try not to define yourself by your bra size. You are much more than that. Try using more flattering terms like voluptuous and luscious to describe yourself.
