Hey! Fellow large busted gal here. Before kids I was a 38J. My milk just came in for #2 and now I'm an even larger 42K. My advice:

-Fuck VS. Like, seriously. Used to work there and they are awful. Their employees are trained to force you into sizes they sell, not what you should actually wear.

-Stick to European brands like Elomi, Panache, et al. Amazon and Bare Necessities are great sites to order from.

-I'm ordering the Elomi Molly underwire nursing bra. I tried wireless last time and it was just not supportive. https://www.amazon.com/dp/B07Y88WQ27/ref=cm_sw_r_apan_glt_fabc_YMRDD3KQBAWKK9D6ZKB8
