The fabric is lovely and comfortable (they are quite long as they state) but although you have an option to choose a size with these belly bands, the S/M just about works for me now at 7 months pregnant. I am normally a size 6-8 and was hoping to use this a lot earlier but it was too big. As a result I ended up buying some belly bands from Mothercare to get me through the last couple of months. It's a shame, as these are not the cheapest option and I won't be able to use them for long now either!
