Last christmas, I got this gorgeous navy bird fabric as a gift. I immediately knew it was going to be a blouse/tunic kind of thing.
I started with Tilly’s Mathilde Blouse pattern as a base. The first muslin turned out okay, but the front neckline sat very tightly while the back neckline was gaping a little. Also, the blouse would ride up when I raised my arms. I fixed this by cutting one size bigger, adding small darts to the back neckline and letting the front neckline out a little at the shoulder seams.
