Oh what a bugger!

It is possible. You will have to follow the program to the very last letter and maybe add in some extra exercise.

Otherwise i suggest telling your friend that way she can come up with other arrangements, is it possible for her to grab the next size up for you??

ETA: And i know what thats like. I purchased a dress off ebay and it was a tad too tight. I managed to lose a few kgs but it was still tight but i just wore some shapewear which seemed to help smooth my lumps and bumps and made it bearable to wear.
