That's very cool! I'm happy to know that you have your eye on that Skinny Clothes Closet, too! It's waiting for you and you will soon be digging around in there more and more.
Whatcha gotta do is as soon as things get baggy, DUMP 'EM! Do not keep them - it is too easy to grow back into them. If your mindset is this: there are no options, there will not be any and you'll stay in your smaller clothes!
I used to have to lie down on the floor and have my husband zip up my jeans with a pair of pliars...lemme tell ya, THAT is humiliating and it makes your stomach REALLY hurt...then when ya have to go to the potty it takes three men and a dog to pull 'em down....
