Bras-Help!!

I don’t know where to really post this. But I breastfed my daughter for a year we recently just stopped breastfeeding. My boobs are saggy.. before I got pregnant/started breastfeeding I was a 36DD-36DDD. I now do not fill out bras at the top I have a gap. I have tried different cup/band sizes and I still have a gap. Does anyone have suggestions are what a good brand/type of bra would be for a mom that has stopped breastfeeding????
