Just kidding but so much want. Sigh. I could wear it even. But I do have some screaming magenta wool-ish with a feathery herringbone weave that could work… I think it is ever so slightly earlier based on seams and fad for analine dyes (fish darts, shape of back, dropped shoulders, shape of sleeves, the flare at the sides not just back, large button… c1874-5?)
But gosh it looks like a lovely snuggly jacket made from polar fleece!
