A plastron is a chest covering which sits over a lower layer. The same term is used to describe a fencer’s chest pad, an armoured breastplate, and a tortoise’s belly. The Plastron shirt is cut with large pleats set under the armholes, forming a pseudoplastron across the chest. The pleats add volume into the skirt of the garment, which is cut without side seams, so that the tails hang freely without weight or stiffness. A single chest pocket on the left and full tailored cuff plackets behind the wrist refer to more traditional shirt making.

Doppler Stripe Cambric is woven in England on an ecru cotton warp with alternating ecru and olive green cotton weft yarns, arranged in a bunched pattern based on the doppler effect of frequency shifting with distance from the wave source. The pattern runs from a wide band of solid green weft to an equal band of solid ecru weft, subtly altering the tone of the dyes across the panels of shirts cut from this cloth.

I'd stop short of saying this is a big human's shirt as William's designs can be worn as you see fit, if you forgive the pun. However, it comes up large, especially the length, so please consider the measurements on the size guide.

Buttons are real shell interpretations of a standard cats eye button, and the whole garment is sewn with cotton thread.
