I am finding the sizing issue with domes for breast pumps a bit confusing. Does the dome have to be a close-ish fit to the size that you are? I mean width and not depth. I am assuming there needs to be ample room to allow for swelling both width ways and height wise.

And does a too big dome spell trouble while pumping? Conversely is a too tight dome damaging also?

This is the pump that was posted by Tibetan but from the sizing I am wondering is it's right for me. I am between an A and a B cup.

Thanks
