I used Depends after my C-section, very handy, very absorbent (more so than pads) and easy. They didn't stick out and make my clothes look funny either. Got all my bras online.
I went to motherhood and bought the underwear, they were about $5 each and thry had a promotion going om, buy one get one half off on top of it. Each is a pack of 3
I bought thr biggest pads I could because after baby you bleed quite a bit. I dont know about the underwear and bras though. Im curious about how much they cost and where to find some good ones too
