Vintage 50s Black Polka Dot Jacket Swing Coat - Luxurious Satin Lining
No inner tags regarding size - Please see measurements: 24" across from underarm to underarm. 26" across at pockets. 17" shoulders. 24" sleeve can be cuffed. 42" long. - Mannequin is 5'8" 32/35/34, this would look better on size M or L probably. Coat weighs approx 2 1/2 pounds.
Side pockets are lined. The detached lining seems is smooth material. I believe the main material would be considered faille with very slight rib.
Flaws: lining has some yellow water spots beside side seam - see closeup. Polka dots are flocked and have some fuzz/wear. Some dots have lost their flock (softness). Button holes have minor wear.
