40 lbs down ,same size!

Options
Im currently 138 lbs, 5 ft 2 and wear a UK size 14 (or a 12 in US sizes). Im a little worried cus i was around a size 14-16 (16-18 US size) when i was 40 pound heavier. Didnt really measure back then but my current measurements are : 34 bust, 31 waist and 39 hips...surely too big for my current weight? My goal weight is 115-120 lbs so i hope to start see a dramatic drop in inches sooner rather than later
