I did exactly the same. Lost 20kg and got a whole new set of clothes. Lost another 10kg and they look terrible. So now I need yet another set! Fortunately I'm down to my bones and muscle with very little fat left so I doubt I can get much smaller... hopefully these clothes will last a while. It does mean that all my expensive work clothes - even my wedding suit thats 12 years old now hang on my like tents. The pants are so baggy its stupid. Even with a belt the pants fold so much they look... odd.
