Bras/ nursing / maternity

Ok ladies help me out. I need bras that are comfortable and don’t make my boobs pop out! I currently use VS t shirt bra? But my boobs are always peaking out and it’s definitely annoying when out in public. Still breastfeeding!

I believe they sized me wrong this last time due to Covid, she didn’t want to get near me… she sized me at a 38C/D. But I always see a lump on the sides that kinda goes in this direction )
