I highly recommend the Solidea pregnancy/recovery range. They have helped me a huge amount after the birth of my little girl - separation and back pain. They feel really nice on. I don't know what material they use but I really like it because it is so breathable. I love that it is a high waist short too cause I wear it under my normal clothes to smooth out the not so desirable 'spare tyre'. they have a graduated compression rating which was a big tick for me. I bought mine from St Vincents Hospital chemist.
