I have a very strong milk flow. When my baby nurses on one side, milk leaks out the other, easily up to 60ml. My bra catches it all, and I feel very dry, which is great and much better than any nursing pad.
I'm deducting one star because it's not like a regular bra. I normally wear a size 36 (German size) and before pregnancy my bra size was 75C-D. I initially ordered a medium, which was okay in terms of the band size, but the cups were extremely tight, especially when my breasts were full. A large, on the other hand, is much too big in terms of the band size, but the cups fit well. I sewed the band in myself, which made it work, but the excess material left pressure marks. Not ideal, but for my milk flow, it's the best nursing bra.
I really hope that more sizes will be available soon, and then I will definitely order again.
