Bend forward at the waist, then slip on the bra and hook it. This ensures your breasts are completely in the cups. The back of the bra should be level with the front.

Make sure the bra is not too loose. You should be able to slide only one finger underneath the band. First, tighten the band, then shorten the straps. Put on a close-fitting shirt over the bra.
