After all that time, I finaly designed a pattern. I've been retouching it a bit here and there so, I'll only post a diagram once it's final. I've pinned the basic pieces together. There are some modifications to be done ; The bodice was too long so I shortened it of about 1 inche from the shoulders. The neckline pulls a little too much because of the breasts so I made the soulder-straps narrower in order to straighten the neckline line and clear the shoulders a little more. So, with a whole inche higher, the tip of the gores sit better on the hips and the neck opening isn't as low. As for the sleeves, I decided to go with a "one piece deal". I've been working on a few layouts so, we'll see how it goes when I do some fitting tests !
