I'll buy one size at Kohl's but go to Target and I cannot get one leg into that same size. I need to go up a size depending on the store.
When I was working on loosing the post baby weight, I kept wearing the baggy pants as long as I possibly could! It made me feel better wearing something that was getting more and more baggy, versus something that fit more snug. I would hold out until I reached some sort of goal before treating myself to something that fit better.
