I have ZERO fall clothes. Not one winter coat. I only have 2 pair of workout leggings. Soon I am going to be hitting all the stores up! Trying to wait as long as possible, so my weight is as low as possible before I start spending serious cash.
Maybe start with a coat that is a little snug when you try it on with a heavy sweater underneath so you can eventually wear it in colder weather w/ layers as it gets loose.
