This is a mens front button shirt with a collar attached on a collar stand and optional front & back yokes.
I found this pattern easy to sew. I just made it more difficult for myself by choosing a fabric with a large, obvious repeat. The fabric is Alexander Henry's "Las Senoritas" and I needed an extra yard to match the repeat on the front sections and pockets. I used a coordinating calico to line the inside of the cuffs, yoke and collar stand.
David, the man I sewed this for, needed a couple of fit alterations. His neck is small and the rest of him is medium. So I cut the neckline areas in the small size and followed the medium size for the body of the shirt. It made it a bit tricky for the armscye because he requested an oversized, roomy fit, and cutting the neck area smaller meant a smaller armhole. So to accommodate a medium sleeve, I lowered the bottom of the armscye the amount taken out at the shoulder seams for the small neck. David is an older man and no longer has the slim, trim boyish waist like the young man modeling on the pattern envelope, I changed the side seams to straight up and down to give him the more ease he asked for and to accommodate the love handles. David also requested a straight hemline instead of the shirt tail style.
Overall I am very happy with how it turned out and anyone with moderate sewing skills could sew this up in a day or two.
