This shirt pattern not only ticks all my boxes - three quarter sleeves with a button tab, raglan sleeves, vertical darts for fitting - but it also offers a little bit more with a looped tab down the front covering the button placket. It certainly adds quite a lot of interest to an otherwise simple shirt. The pattern is 10/2008 #113 which I can't see is available for download, but if you ever see this issue for sale I can highly recommend it, there are quite a few good patterns in it.
That looped strip was really quite simple to make - it's essentially just horizontal lines sewn to the shirt halfway between each buttonhole, and then press the fabric downwards towards the hem.
I did mess up the sewing order though - the strip should have been added before the collar, so that the top end of the extra strip would be enclosed within the shirt stand. I added mine after I had sewn the collar on, so I've done a dodgy fix of just topstitching it close to the collar stand seam line - it's clearly visible in the photo below but I doubt anyone else will get close enough to notice.
The fabric I've used is a thick textured white cotton that is probably a bit too stiff for a shirt, but it helps give the looped front and sleeves a bit of structure. It means the back puffs out a bit, which I could fix by making the vertical darts a bit deeper, but I think I'll leave it because it's not too bad.
I also find the way the raglan sleeves meet together as a point on the shoulder very satisfying - it's those little details that people who don't sew will never see but it makes me happy.
I found the sizing of this shirt to be quite generous - I made my usual size 34 at the shoulders and grading out to a size 40 at the hips. There is a lot of excess fabric around the arms - the armscye sits quite low and the sleeves are very wide. I think in a softer fabric with more drape this would be fine but it does feel a bit bunchy in this thicker fabric.
I think this is a fantastic pattern, and I can't believe I waited so many years before I made it! I think the loop strip could be added to almost any shirt pattern, and ribbon could be used instead of the shirt fabric so possibly another one of these style shirts is in my near(ish) future.
