4 RULES OF THUMB:

The backpanel

The straps

The cups

The clasps and the front piece

The straps

Straps must not be so tight that they pinch the shoulder or so loose that they fall off the shoulder.


CORRECT	STRAP PINCHES SHOULDER	STRAP FALLS OFF SHOULDER

How to respond?

If the bra pinches the shoulder:						If the strap falls off the shoulder:
Lengthen the straps with the strap adjuster.						Shorten the straps.
If you feel that your breasts are not being given adequate support, try a bra with a smaller band size.						If this does not help, try a bra whose straps are attached more at the middle of the cup and/or back panel.
