I am currently trying to finish this dress, Butterick B5281, and am really struggling with the neckline.

I’ve read the instructions several times and I still can’t make sense of how the neckline should sit. Version A appears to be on an angle but Version B (short sleeves) looks to be straight. The line drawings on the back are no help either. Then there’s the pleats on the shoulder; they tend to create a curved edge rather than what appears to be square. Arrrgh!!!

I’m already on my second try at squaring off the neckline but am making a right mess of things. Has anyone else made this dress? If so, any suggestions on how to finish the neckline? It’s driving me nuts!!
Thanks in advance,
