The band is the most important part of the bra as it provides 80% of the support.
It should be fastened on the outside or middle hook, and should sit straight across the back.
You should be able to slide 2 fingers under the band. If you are unable to do this comfortably, the band is too small.
If on the other hand the band feels loose or rides up your back, then this is a sign it is too big.
