How tight should the bra be?

The Lilu Massage bra is highly adjustable around the waist and the shoulders to give you extra support while pumping. To optimize the massage provided by the massage cushions, the bra needs to be tightly secured around the waist (ex. it needs to be tightened so that you can't easily fit 2 fingers between the bra and you ribs in front). Once secured, you can adjust the shoulder straps until the bra is tight enough, so it feels like a hug.
