Sister sizing

All bra sizes have a set of “sister sizes”. These are alternate sizes where the cup volume stays the same even though the band and cup sizes change.

Sister sizes can be used when your top fits perfectly in the cups, but is too tight/loose in the band, or to find your fit in our one pieces if you wear a different top and bottom size.

Your sister size can be determined by a set of one-size shifts in opposite directions. When you size up in the band you size down in the cup and when you size down in the band you size up in the cup.

For example, a size 32DD could also wear a size 30E or 34D.

Let us explain...

Cups fitting perfectly, but the band is too tight/loose? You will need to sister size to find your fit!

When you size up in the band you size down in the cup and when you size down in the band you size up in the cup.

Here are some examples on how to get the fit
just right in our swim tops, if you need to try another
band size but maintain the same cup size.

Our one pieces are best fitted to the body first and then adjusted according to your bra size.

So, if your dress size is bigger or smaller than your bra
band size you will need to sister size.

Here are some examples on how to find your fit in our one pieces if your dress/body size is different to your bra size.
