Recommend your post surgery compression garments!

I'm having a MMO on may 21st and have really appreciated this site leading up to my surgery date. You ladies have been wonderful!I want to order my post surgery compression garment and was hoping you could recommend the ones that worked for you and why. There are so many options out there and I don't want to buy a $80 compression garment if there is a more cost effective one.Also, how do you know what size to buy? I'm a size 8 now but I have an apron so I'm not sure if I will still be a 8 after my TT.
