sought-after ! Inverallan Indigo Allevol Special secure Knit Cap Cotton UK Vintage Indigo Dye

This is an indigo knit cap from Inverallan, purchased about 10 years ago from allevol in the UK.
It's a charming item with little wear, as it was used a few times and then stored. I wear a 7 3/8 in latest Era, and this feels a bit tight. It will stretch with wear, so it might be okay for larger sizes, but that's the current fit.
It's still a deep navy blue and a truly cool knit.
I think it's a valuable item.
