I bought button up tops and yoga pants I could pull up. The first couple of days I just wore the long tops so I did not have to pull anything up. When I woke up the ace bandage (some surgeons use this) and my surgery bra had blood on it. But I never had leakage. Some people have leakage and it may get on your clothes. Below are the clothes and gauze/pads I got on Amazon if it helps.
Below are Amazon links of things I got... Some things I found out only after I was home. I am now 3 months PO. Your Dr will give you pain meds/all prescriptions ahead of time. Fill them ASAP so you have them.
Favorites: Flexible ice packs - ones below keep cold for a long time and fold up to take up less room in the freezer. Also the silicone straws - they go to the bottom of a big smart water bottle and were life savers! I could not pick up the bottle for a few days. The pregnancy pillow did not work for me so I wasted money on that one. But alot of people love it.
Zip up sports bra - Comes in a 3 pack
Button up sleeping shirt/day shirt - I wore just these for the first couple days so I did not have to bend over and pull up my pants
Silicone straw for smart water bottle - Amazing if you can not pick up a big bottle at first
Flexible Ice pack - Stay COLD for hours
Silicone scar sheets - There is a cheaper brand but it feels more like masking tape.
