I am thin, but with large breasts...I don't fit any of the bras they have in the Motherhood Maternity store. But I used the International Bra Size Converter by measuring myself at home and was THRILLED to find that they have more unique sizes online! My ONLY issue with this bra is that based on the size the converter told me I was, I should have gotten one size up around (not the cup size). As it is, however, I ordered some NuAngel bra extenders and they worked perfectly. In fact, I think this will work out even better, because as I continue to lose weight through breastfeeding I can simply take off the extender, and not have to buy a whole new bra! (Much cheaper.) Would totally recommend this bra- it's confortable, a soft fabric that does not show through your shirt, and thick enough that you won't [excuse the term] nip out, which is embarrassing!
