Vintage Ungaro Blazer, 1980s Purple Zig Zag Wool Jacket with Velvet Trim Size S.
Fantastic vintage blazer by Emanuel Ungaro has a funky zig zag design, velvet lapels, braided trim, and a double breasted closure. I absolutely love this for so many aesthetics! Obviously amazing for a sort of dark academia or goth look. It reminds me of a more serious version of a Master of Ceremonies jacket. Has a pointed hem at the front, the braided trim all around the collar and hem, and it has a lovely fitted silhouette.
The only tags on this are for the brand and the "Made in Italy" designation. The weave is wool, and I am not sure what the velvet is but I imagine it is cotton. The jacket is fully lined, and does have two pockets - but the pockets are so small that I don't consider them functional.
No size is marked on this, but I would say it measures like a modern size small or 6. For best fit, please compare the measurements below to your own, or to the size chart of a brand that fits you well.

Chest: 40"
Waist: 34"
Across shoulders: 13. 5"
Shoulder to hem: 19"
Armpit to cuff: 16. 5"
