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.
Getting the right sized Breast Shield is key for comfort and performance. This is based on the size of your nipple only (not even the areola!). Each Elvie Pump comes with Breast Shields in two sizes (24mm and 28mm) and a size guide on the Breast Shields themselves so that you can find your best fit. We also have an additional, smaller size (21mm) available separately, if needed.
