First, I found this pink, French-cuffed shirt by Alfred Dunhill of London. It fits, though a bit tight in the neck, and has real MOP buttons, not cheap plastic ones.
Next, I found this RL Polo dress shirt, also with nice buttons.
Finally, a trip to the ladies section netted this silk pocket square. That's usually where such things are found, because thrift store employees rarely know much about clothing.
