Hello stephanie,
That's great news, doesn't it feel wonderful, and welcome to the wonderful world of women's sizes. It will become a lot easier as you become more comfortable with your body and the size of clothes that fit you. You will also find out that what fits in one brand name will not fit in another. When I buy cloths from Sears, from the "Jessica" line, I need to buy a size 4 in pants and skirts and a size 6 in tops. However any other brand I usually have to buy a 6 in pants and skirts, or an 8 in tops. So when ever possible make sure you try things on before you buy. Buying on line is a great way to go when you are first starting out as you can usually return items for a full refund if they don't fit, just check their refund policy.
Have fun with your new wardrobe. I'm sure there will be lots more to come. Remember "when times are rough, shopping is a great form of therapy". Well it works for me.
Chat later,
Steph 🙂
