What is
SISTER SIZING?
"The most comfortable bras
I've ever worn — true to size
and great shaping."
Sister sizes refer to bras that have the same cup volume but
different back and cup sizes. The beauty of this method lies
in how it provides flexibility. If a bra feels too tight or too
loose around your bust, Sister Sizing allows YOU to fine-tune
the fit without compromising on the volume of the cup.
When to use
SISTER SIZES
Sister sizes are ideal if you're in between sizes,
experiencing slight discomfort, or finding it hard to get the fit
you love. With sister sizing, you can adjust the band and
cup size while maintaining the same cup volume.
DO SISTER SIZES
REALLY WORK?
Yes, they dol If you go up a band size, simply go down a
cup size, and vice versa. For example, if you usually wear a
32F, you can try a 34E or 30". Sister sizes Offer a wider
fit range, allowing you to find the best possible comfort and support.
