Vintage coat w/ruching & gold bead detailing

Vintage coat w/ruching details & gold beads on the front/collar. It’s in excellent condition overall except for 2 areas, refer to last 2 photos. 1) Right sleeve button is slightly more worn down/fuzzy, it’s hardly noticeable & blends into fabric. 2) There’s an exposed hole along the seam between the left shoulder & collar, due to loose thread. No size tag, so approx flat-lay measurements are: Pit-to-pit: 22.5-25” Waist/band (tapers in fr pit): 17.25-20” Length: 21” Arm length: 23”
