I bought a nursing bra but I meant to buy a regular one cause Ive always needed the underwire for support (#big boob probs 😧) and it is the most comfortable thing I have ever worn 😱😂😂 I may never go back! 😂😂
Thats why I had to order mine, they have bigger sizes online.
I ordered it from motherhood maternity, warning you though it wasnt exactly cheap.
Where did you get it I have big boobs and have not found a nursing bra yet 
I was able to find 46 ddd at the Hanes store. it was the biggest size they carry! hopefully mine don't get any bigger.
