I'm having a similar issue right now. I have to have clothes for work but nothing is fitting right now. I'm determined to keep up my fitness routine so I know if I go buy something it will only a short while that I will be able to wear it. I can't afford to do that every few weeks. I've decided to buy a few new things like pants that I will need for work, but I'm also digging out old shirts that I haven't fit into in years. I had some boxed up. It's a really good feeling to put on something that once upon a time I really liked but didn't believe I'd be able to fit into ever again.

Next week I'm going to hit a thrift shop or two to see if there is something decent that will fit me right now that I don't have to spend a fortune on. I figure I can wear it for a few weeks then hopefully re-donate it again.
