Vintage YSL Black Tuxedo with cummerbund & suspenders tailored in the USA. It has the union label. This was purchased from United Formalwear. It is 1 button with satin lapels & buttons and satin strip on the pants. It’s a 43L 37L on the tag but it’s customized. Approximate measurements are shoulder to shoulder 19”, armpit to armpit 22”, sleeve 26” and base of the collar to end of jacket is approximately 31”. The pant waist approximately 36” with a 30” inseam. The waist at the button is approximately 42” and the pant rise is approximately 13”. Look at the pictures. It is wool, beautifully tailored. I researched and same tuxedo is over $500. Offers are welcome. It’s in good vintage condition & possibly better.
