I have a stunning Eidos one-piece collar popover in teal from the SS16 collection for sale. The collar is the selling point, one-piece with a seamless flow from the placard to the collar itself, beautiful. All buttons are white mother of pearl: one on the front, also on each cuff. This is a size large, but it is in reality a medium ~20-21 inch p2p (Eidos sizes small)
The a slightly bluer version of the close-up pic is a better representation of the color.
Thanks for looking~!
