Maggiemay22, great that you found Asda to supply at a decent price and comfort. I wish you a smooth, fast recovery and I too wore my usual pants with them. It's when nature calls and pulling the crotch over that can be difficult.
I've used support knickers from Sainsbury's, TKMaxx and bought them onsale at John Lewis. They all worked fine and having a cotton crotch insert was the most important factor for me, oh and not too tight or too loose, afterall, they are worn 24/7 for a bit.
I'm due to have lipomodelling soon after having a lumpectomy and re-excision last summer and was wondering if anyone who has already had it done could recommend any particular brand of support knickers. I don't want to waste my money which is in short supply!
