C section wound.

I’m not plus size but all my extra skin from twin stretching just dropped and hangs because I lost weight while pregnant
I’ve found the cheap Asda breast pads folded in half a life saver to stop sweat & rubbing on my wound. You can also use pads but I found they just fell out but that may be because I don’t have a true apron
Just make sure you change them soon as they start getting wet

Use a maternity pad, fold it so the sticky side sticks together and place it between your belly and your scar when sitting down for periods of time. As they are absorbent they will help keep it try and stop your skin sticking together.

Thankfully recovered from mine before the heatwave but that was a tip a midwife gave me after my first was born and it really helped.

I sit infront of the fan just before I go asleep and just hild my belly up for a couple of minutes, during the day and night, ive cut the centre bit of the maternity nappies out and used that between the apron, its long enough to cover and wide enough that the whole under apron and both sides of the incision are covered, I had so many left that it felt worth using instead of wasting the money for pads etc
