Hey there Luana,
That is such great news, you seem to be making progress, and you also seem to be genuinely happy. It does make you feel good when you are in control of your issues and you are able to go forward without the fear you once had, not to say there won't be scary times ahead, as there will be. Like you, one of my own next steps is voice lessons and I have to contact the hospital on Nov 26th, so like you I'm anxious to get started.
On the clothing side there are many ways to go, and it's really up to you and your comfort zone. There are the second hand clothing stores which is a good place to start as prices there are a lot lower, but selection and quality may be lower also. There is online shopping, eBay etc... but I'm not sure of guarantees should cloths not fit. Then you have catalogue or online catalogue shopping such as Sears, where they have a great selection, including sizes, and styles, and their return policy is usually no questions asked. Then there is actually going into retail stores shopping for new, and this depends as I mentioned on your comfort level. In this case it's good to have someone to go with you who can help with sizes, what looks good what doesn't etc... and to run general interference

So again congrats on your progress, it's great to see.
Chat later,
Steph
