debbie... here's a news flash: FASHION BUG CLOTHES RUN SMALL!!!!
you will NEVER be able to actually see yourself unless you PRACTICE. that means you have to LOOK at yourself. and you'll need help to do that.
and believe me, i know exactly what you're talking about. i catch sight of myself in a window, and can't figure out where i am!!!! i feel like a vampire, in some respects!
but back to YOU.
here's a thought: make an appointment with a personal shopper at a nice store, like macy's or lord and taylor or rich's or whatever. when you make the appt, a few days before you actually show up, tell her what's happened!!!! throw yourself on her mercy!!!!! give her a spending limit, and she'll line up a whole bunch of clothes for you to try on. privately. with her holding your hand the whole time.
the last time i was thin, i was wearing a size 10. i went to a 'tiny' person's store, and tried on a size LARGE dress, and it was waaayy too baggy. i asked the sales lady to get me a medium, and she insisted that it would be too small... i actually snapped at her.
and when she saw it on me, her jaw hit the floor. it fit like a glove. and when i reached my heaviest, i doubt that i could even have fit one leg into it!!!
so, i guess what i'm saying is basically this: rely on the professionals for help, not the floor sales staff, and certainly not on yourself since you can't really see yourself.
and please PLEASE let us know how it goes... you're so very very close to your goal, and i'm so proud of you...
