Pattern making and converting an oversize henley nightshirt to a semi-fitted shirt

What I did:
Purpose:

Before

I have lots of nightgowns, but only a few shirts that fit me well. I decided to turn this oversize nightshirt that had been my Grandmother's into a shirt, shaped to fit me just the way I prefer. I liked the henley style neck and buttons of my Grandmother's nightshirt and wanted to retain these on the finished shirt.

The Process

I didn't have a pattern of the sort of shirt I wanted, so I made one, based on two shirts (see pictures below) with elements that I like.

Process: I based my pattern partially on this brown shirt because I like the shaped side seams (slightly smaller on the waist and wider at the hip) and the tunic length.

Process: I heightened the shaping of the brown shirt just a bit by taking the upper waist in with a safety pin, and copied this silhouette for my pattern.

Process: I like this black shirt (from the Somerville Homeless Coalition's 5k several years back) for the way it fits around the shoulders and sleeves.

I made the pattern by mashing up the measurements and outlines of these two shirts and adding seam allowance. I then plotted these dimensions and drew lines connecting the dots on a large sheet of paper, eyeballing the curves between the dots. The paper was upcycled: it was the packing material from something that I had bought. I cut out the paper along my drawn outlines and then used my pattern to cut out a front, back, and sleeves from my grandmother's nightshirt.

Here's a progress shot of cutting the turquoise nightshirt into the new shirt, using the pattern I made. The green object in this picture is a knee pad, given to me by my mother-in-law. It was designed as a pad to kneel on while gardening but it also works very well for protecting my knees while cutting out pattern pieces.

After

The finished shirt looks more or less how I envisioned it. I didn't get the pattern 100% right in my initial cutting. The neck was too tight and the sleeves were too long. But I was able to fix these issues by sewing into the seam allowance a bit to widen the neck and using a very generous hem for the wrists; then I went back and corrected the paper pattern. I was satisfied enough with this project that I'm planning to use the pattern again, refining or adapting it further as needed.
