Well, this wasn't really the easiest task. The pattern really isn't made for my body... Luckily I followed instructions and started with the muslin. I got some old sheets from mom for this purpose and I cut the first one up. And then I started sewing the muslin. Well, there were some problems:
In the first picture, there's the biggest issue. The back is just way too big. The same thing can also be seen in the middle picture, but there's the other thing. My back is crooked, so all skirts/dresses/pants look like their crooked on me. I'll try to fix this. And then some smaller issues at the bust area.
I tried to follow the instructions on the book and I think the back got a whole lot better when I did the sway back alteration. I didn't have to correct the skirt part, since I really don't have a sway back, the back was just too big. I know Lladybird at least had the same problem. Her's turned out really awesome... For the skirt looking crooked, I cut more from the side that looks longer, I think it does look better (no pictures from the later fittings...). I think I got the bust area corrected as well, but we'll see. Mainly I just made the darts a bit bigger and this seemed to correct the problem and I also took in the side seam a bit. Hopefully this will look good in the final dress. It seemed to work on the muslin at least. And if there's as much leftover fabric as with the meringue skirt, I can always make the bodice again... I think I will try to cut the real dress tonight, but the sewing I will do next week.
