This jacket, which I found at a boot fair, is everything I love about junk-shopping, flea-marketing, op-shopping and general second-hand-rose-ing.

It’s not just the low price, delicious although that is, it’s the uniqueness and serendipity of it. No one else can buy this jacket, in fact it may even be the only one of its kind ever made.

The clue to that is in the label, Hildegard Escher Couture – combined with the quality of the fabric and the superb workmanship.

The fabric is very soft and incredibly light. I would say it definitely contains cashmere, possibly even vicuna.

I keep stroking it, the feel is so glorious compared to any other garment in my wardrobe, let alone the polyester LCD (lowest common denominator) that has become normal.

As for the details, I love the slopes on the pocket flaps.

But it was the buttonholes that first caught my eye – because each one is edged with a tiny border of the fabric, creating a ‘bound buttonhole’. Or to put it another way, a unicorn.

I’ve just looked at all my other jackets and even on the proper designer kit the best is a perfect border of shiny overstitching. On a cheap Zara blazer it’s pretty rough overlocking.

Even on my husband’s ravishing vintage Yves Saint Laurent suit it’s stitching and on a Savile Row suit they are finished by hand using buttonhole stitch (like a tighter version of blanket stitch), over a piece of fine cord.

You can watch the process in this thrilling video, from Anderson & Sheppard, where the King gets a lot of his suits made.

So a properly-done stitched buttonhole is a glorious thing, but a bound buttonhole means my jacket was bespoke. So I got onto our friend Google and found that Ms Escher is a Swiss couturier, based in Zurich, still active.

There is an article about her on this link to a local newspaper, which mentions the word ‘Hollywood’ but the rest is in German, beyond my two year’s study at school, although I think the headline ‘Kleiden machen Leute’ is a play on clothes maketh the man.
