Perfectly fitting bra means having the snug fit at the band and big enough cup size, but the right size is only half of the success. Essential is the right bra type and shape of the underwire and cups, and what is critical in case of larger bust, full support. Very important are used types of supports, thickness of the straps, number of hooks and type of the fabric. The combination of all the features make our breasts wonderfully supported.
Wearing that proper bra causes so-called migration of the breasts i.e. moving fatty tissue from underarms back to the breasts, and improving shape and firmness of the breasts as a result.
Wearing the wrong bra may damage and speed up aging of your breast. From 85% of all women wearing the wrong bra 70% feel the pain not only the of breasts, but also of a spine. But the wrong bra means not only discomfort. It is to a large extend permanent deformity of our breasts.
