I made some more tweaks to the simple summer shirt pattern: rounded the armscye, tapered the sleeve, added a topstitched French placket, and lengthened the hem. I mismeasured the placket width and made this shirt a little too blousy but I’ve taken the pattern in so the next one will be better. This particular shirt also has lapel facings, but that detail is too fiddly to qualify as “simple”. I think I’ll reserve this design for fabrics which don’t have a clearly “wrong” side, then work up a variant with a banded collar which will work better for prints and the like.
