That is brilliant Frabjous, thank you so much for taking the time to analise my muslin. I was thinking of moving the front dart out to the side (closer to the hip) by an inch to try to get rid of the wrinkling effect of the material, but maybe I will try your suggestion instead (easier than a diet). I intend to add more fabric to the back hem as I noticed from the photos how much I piched forward but I wasn't sure if that would make a lot of difference. However you suggest it will make a difference to the ballance so I'll give it a go. I worry a little about the wrinkling at the back opening, my back seems to be arching back (concaving) so maybe I have too much fabric there, I just don't know how to adjust it (I will think on this a bit more). I think I will tackle the side seams, the hem and the front dart and see how that affects the second muslin and post more photos for people to guide me further. Thanks for the advice, it is much apreciated.
