MOH / Bridesmaid dresses 2 months postpartum

So my sister is getting married in September, approximately 2 months after I (MOH) and 1 of 2 bridesmaids give birth. She’s given us pretty much carte blanche on the dresses just asking we choose same color from same company. I’m leaning toward azazie since it has a large selection, but wondering if anyone had any styles to recommend that worked well postpartum? My chest has always been large so I usually need to order a larger size for that and take everything else in, not sure how I can accurately get chiffon tailored when my stomach/waist is a big TBD. Also trying to find styles that can accommodate an actual bra since I’ve got 34Gs and will likely be breastfeeding, cant deal with tape and crazy corset options.
