Bra hooks explained
Get the best fit from your bra by using the hooks correctly. When you first buy a bra, you should be able to fit in two fingers between your back and the band while wearing it on the on the first set of hooks.
As you continue to wear the bra over time, the elastic does start to stretch. As the band starts to feel a little loser, move to the next row of hooks. Once you starting wearing your bra on the last set of hooks and you can fit more than two fingers in under the band, it’s time to replace your bra.
