Frequently Asked Questions
What's the difference between band size and cup size?
Band size measures the circumference of your rib cage (underbust), while cup size measures the difference between your bust and underbust measurements. Both are equally important for proper fit.
What are sister sizes and why do they matter?
Sister sizes are bra sizes that have the same cup volume but different band sizes. For example, 34C, 36B, and 38A are sister sizes. They're useful when your usual size isn't available.
How often should I get refitted?
It's recommended to get professionally fitted every 6-12 months, or whenever you experience weight changes, hormonal changes, or if your current bra no longer fits properly.
Do European bra sizes fit different than US sizes?
Yes, European bras often have different cup ratios and band constructions. A UK 34D is different from an EU 80E even though they represent similar volumes. Always try on before purchasing.
How should a properly fitting bra feel?
A proper bra should have the band sitting parallel to the ground, cups fully covering breast tissue without gaps or spillage, and straps comfortable without digging in.
