Let me tell you about this Smoking Jacket. I looked all over the place. I finally found the jacket i was looking for. But the sizing was very hard to understand. SMALL/ MED. or LARGE/EXTRA LARGE. I chose large/ x large because people suggested that i pick that. but, i am 5' 7"" 35 " waist and the SMALL/MED. IS PERFECT. LOVE THIS SMOKING JACKET. THANKS BELT OUTLET.
