These are great! I purchased a 3 piece binder set from Amazon, and I much prefer these compression panties. The binder was too restrictive and it wasn't comfortable as I was up and down nursing newborn twins. I found these very supportive and true to size. The compression actually allowed me to forget to take my pain meds today. I feel all tucked in and supported during my recovery.
I will likely buy another pair or two to add to a rotation. I may wait to see if it helps reduce my tummy and size down if needed as I'm only a week and a half postpartum.
I've been wearing these all day and they have not stretched out. They don't roll down when I sit.
I've found it helpful to lie down after pulling these up to let your tummy "settle" while pulling the compression panties open a bit. Then when you stand up, all your tummy is lifted to where it needs to be. Or you can pull these on while lying down....same effect.
