wear them as long as you can, and then pick up some items from second hand stores or the cheap sale racks at WalMart. You are going to drop at least a size every month, so spend as little as you can,
Fortunately for me, the hospital provides the scrubs I wear at work, so I never had to buy work clothes. Sure was fun to watch the sizes drop from XXL to SMALL!!!!!!!!!!
It's a great time to rethink your final wardrobe - like what color palette you would like. I often bought large clothes just because they fit - not necessarily because they went with anything else I had. It was so fun to get rid of the color catastrophe and choose pieces that complemented each other. Makes my closet smaller and much more coordinated.
