Don't worry--I was close to your size when I started and I stayed in the same size clothes for awhile, just more loose--then I woke one week everything was falling off me. I was a 30/32 bottom, 26/28 top & bottom and nowI wear 18/20 bottom, and 14/16 top. As I exercised I loss more inches and made me fit into smaller sizes even when the scale does not show it.
