bridesmaids dress 6 weeks pp

Lo
Hi! I am due July 5 and I am the maid of honor in my sisters wedding  August 9th 😲. Do any current moms have any advice about what my body will be like? I know everyone is different but I am curious what other peoples experiences are. I was a size 6 pre-pregnancy, should I just order a few sizes bigger or try to order maternity? Thank you!
