Pads/Underwear for postpartum??

Kayla • Married & we had our perfect baby boy on 03/21/2015, Pierce Huntlee. He was 7lbs 10oz, & 19.5 in 💙
I'm getting very close to meeting my son, first time mom here. I seen a post earlier this week about disposable underwear that actually looked like real underwear, I cannot find the post anywhere! Just curious what type of pads or underwear were best and most comfortable. I know they give you those mesh underwear at the hospital but I've also heard they don't stay in place. 
Any advice appreciated! 💙💚💙
