3 Fat Chicks on a Diet Weight Loss Community

I'm not quite to that point yet.. but as a poor girl paying back student loans, I know that as I lose, I'm going to need to go buy some smaller clothes (YAY!). I would rather pass on my current size, to someone who has lost weight and now needs that size.. does that make sense? Has anyone done anything like that? It would be kind of interesting if it could be made into a yearly or a bi-yearly event-- like.. the Size Swap.. I trade my 20s to someone, for someone elses 18s..etc... Just a thought !
