I sometimes need to wear a quarter cup bra when I am extending my nipples by wearing my long size suction teats.
For all day wearing I need under bust support, and I need my nipples free, but not droopy!
I bought a couple of pretty bras from pabo.com.
They don't give much pushup, so I suggest trying the bustier variants:
I still need a proper cupped bra when I am using my full breast pumps, as the quarter cups don't hold the flanges properly.
