Perfect for the occasion
Size: Small, Color: Purple
Fit was great and true to size. I am 5'6" 140 lbs. and wear 38S jacket. Ordered a small. Bought this for a "Prom" theme party. Everyone commented on it. It's not a high quality garment. But for something like new years eve party or a night out in Vegas it's perfect.

Great quality jacket
On stage presentation in this jacket was fabulous. Great quality. He did have to buy a larger size to get the sleeve length but a tailor fixed the shoulder to a perfect fit. Will buy again in another color.
