Just wanted to let you all know that I have bought one of those 'belly bands' that go over the top of your trousers - making your tops appear longer (makes non-mat tops wearable!) and allow you to wear non-mat trousers for longer (as you can leave the top buttons undone, covered with the band).
Not trying to sell the things but really they are good! I am now wearing a pair of jeans I have not been able to get on for over 5 weeks, with the top button undone but the band covering it all up.............I bought mine from a girl in Australia via Ebay for about £8 (inc postage!)
She has loads more up for sale and I really can't recommend them enough!
