Will Elvie Pump work with all cup sizes?
Elvie Pump has been designed to fit within a standard nursing bra and the cup size makes no difference to how Elvie Pump works.
If you are using a particularly structured and inflexible bra, the Bra Adjuster may be used to create more room.
If you're thinking about fit, we'd recommend using our Breast Shield sizing tool. Using the right Breast Shield will help with comfort and milk volumes.
