I was at Epworth Freemasons end Feb for lumpectomy, but only stayed in 1 night. I was provided with the moon cushion as @TonyaM described above from Zonta. And I know Zonta also provide bags for the drains - however I didn't need them. Open front PJ are definitely good. If you want something more in the realm of loungwear you can always try Boody - their products are soft, but maybe a little pricey for some. But look less like daggy pj and more like something you can even wear home from the hospital. Best of luck for your op.
