should I even be buying girls cloths before hormones.

Sure but don't go too crazy. Money can be an issue, so watch you wallet. The clearance section in real stores and online sales can be your friend. I currently wear size 11 and large stuff but I am 6'1", 180 lbs, and have a 38 chest due to a protruding sternum. My feet are just a little too big for buying shoes in real stores (12W) so I use the internet either amazon or ebay.

Clearance is your friend! When I got started, I bought from the clearance sections of clothing stores and got some really good deals, and I've even been able to make some of those clothes work with the way my style has evolved. Like others have said, you'll probably find yourself buying new clothes periodically anyway.
And you never know how HRT will change you. I started HRT when I was 30 and I expected next to no body changes, and I have crazy hips and booty now. lol

I like consignment stores, I have gotten some good brands really cheap so far... even can find designer labels on the cheap.

I'll have to try some of those. There should be tons around my area. Thanks.
