Do you wear a bra?

I see a lot of comments about how folks who EP wear a bra all day long. I am 4 weeks pp and only put one on to hold the pump every 3 hours or when I leave the house so I feel like a human again lol. Do you all wear bras for convenience, or comfort, or something else? I’m big in the chest dept so it’s weird for me but I can no longer stand wearing a bra all day, it makes me really sore and I’m terrified the pressure is going to give me a second round of mastitis. I’ve resigned myself to just leaking milk all over my shirt and pants and floor until that stops haha. Is this going to make my boobs super saggy in the long run?
