I have never seen this in shops before but when I walked into River Island and saw it I was taken aback.
The collar was £10 and the size of it is big enough to cover even the deepest of shirt necks, successfully covering up to your shoulders.
The material is a good quality, thick white cotton, and has gold spiked stud buttons to decorate. Luckily it is one size fits all!
I have found it to be a great use under all types of tight jumpers were wearing blouses or shirts underneath would be too uncomfortable.
What do you think of it?
