Bra help

Girls I’m hoping someone can guide me here. I gained nearly 60lbs with my first baby and went from a bra size 34B to 36D. Now Ive lost 50lbs of it and just 10lbs away from my pre pregnancy weight.

As far as the bra size, I continue to wear 36D but I buckle it on the first hook (the tightest part).

I find that the cup size gives me a spill over so I just got 36DD to see if that would help but still feel I have some spill over. I know if I go higher on the cup size past DD it would be too big. I feel that the jiggly-ness of the breast makes it an even bigger issue since my breast aren’t as tight as they used to be and slide out of the cup.

Anyone have this issue? How do I fix it?
