Shrinking out of your clothes is a double edged sword when you're losing weight. It's great to know that you now fit smaller sizes, but if you live on a tight budget and plan to lose a significant amount of weight, it can be difficult to justify buying clothes that you hope won't fit you for long. So, you wear baggy pants in the meantime.
Pants that used to be too tight are now a size or two too big. I wear them anyway, and hide them under baggy shirts. I don't want to spend money on clothes until I get closer to my goal weight and size. Since I work from home, I can usually get away with this.
The one thing that I have learned the hard way, however, is that while a belt may hold up baggy pants, there isn't much you can do about the skivvies underneath that keep slipping down because they're two sizes too big.
