It is easy to become obsessed with the idea of single shirt, one with two pieces, no facings, not even set-in sleeves. What can be done with this idea? How can two flat pieces joined together in four places accommodate a grown woman’s torso, not at all flat, and with arms often in motion? It’s just the same thing over and over, like when I used to listen to music, always stuck on a track, just this time in flannel, that time in linen, so many double pointed darts around the waistline cinching it in (platonic ideal).
