So I've nearly finished, and I managed to make a massive cock-up, which was luckily rectifiable.
When I traced off all the skirt pieces, I managed to make a ridiculous error. I diligently wrote on the pieces the pattern name, that I'd adjusted it, added length etc, but I forgot to write which bloody pattern piece was what. I am a royal idiot. They all look the same.
The front was easy to choose as I'd put the OTF marking on it. But the others? I grabbed my toile (luckily I'd not chucked it) and slapped it down on the table, laid each piece on top of the toile and went "yeah that looks like the side piece". Why didn't I just walk the tops of the skirt pieces with the bodice? No idea. Cos I am lazy.
Turns out I got the side front and side back pieces mixed up, or at least I think that's what's happened. When pinning together the skirt pieces wouldn't match up with the side seams. I started with the back so I put a pleat in the middle of the piece. It looks odd but nobody will notice but me. When it came to the front side piece it was the bodice that was too long. So I figured I'd stick another bust pleat in. At least this works with the "style" as it already has a waist pleat for the bust. It looks a little odd too, but like the other pleat it's likely only me who will know. I now need to check whether that was actually right or if I'd made a different mistake. Sewing is like being in a crime thriller where you are the detective but also the murderer.
Anyway, this dress is hardly even the original dress any more with my wrong neckline, extra pleats, gah. Oh well, it fits nice! I've decided I don't need the side zip. The fabric is soft enough that I can get out of it pinned up anyway, but I will make the front button band as real buttons so that I can undo it to give me more shoulder wiggle room, that was the only bit that felt a bit tight when wriggling free (and I HATE sewing zips).
