I put on a pair of pants this morning that I bought just this spring for a lot of travel. They fit when I bought them and were even a little bit snug by the time the travel was over.
Then after the travel I got serious about getting fit. Put the pants on for the first time in two months this morning and they were definitely loose. I went to the farmer's market and had to buy a belt when I was there to keep them from falling down while I carried bags of veggies!
