"Casual" is an unlikely name for this very high collar which suggests it is what the Edwardians wore when relaxing at home. We dread to think what they adopted for really formal occasions...
The stand is 2¼in high. The turndown 2½in (6.5cm) at the back with the front point almost 3in deep.
This collar has been folded and marked, with a cold wash at 30 degrees and a gentle press (no steam), this collar will still have fantastic character.
