Post baby clothes

Ladies, need some help particularly from those of you who have had previous babies! 👶 I have a family wedding that is 6 weeks after my due date. I am under no illusion that I probably won't be back in my pre-baby clothes but would I still fit comfortably in a maternity dress that would also allow me to breastfeed easily? Or would I need to buy an outfit that is not maternity, just a bigger size? 🙈
