Vintage "Jockey Silk" Riding Jacket

Vintage 50s 60s jockey jacket / jockey silk in red and gold. This incredible satin-like jacket is well worn and has old repairs, particularly to the collar, cuffs, & shoulders. The horse-riding jacket, while clearly used and loved, presents beautifully. Three pockets with pointed gold details and red buttons cascading down the front. It's a great find that one doesn't come across too often. Shown on women's XS (32.25.36, 5'8"). It would work for a variety of sizes depending on desired fit. PTP: 20" Waist: 15.5" (14.5" belted without extender) Length: 28" back of collar to hem Buttons were moved in to extend size when I purchased. I've returned all but the top one to their original position, but you can get an extra .75" by moving them back. Two spare buttons available as well--one in a pocket and other sewn into the belt. It once had buttons on the cuffs but no longer does. Age (~ 1950s) & material (satin) are merely my best guesses and aren't guaranteed. Please see pictures.
