This is my Dainese leather motorcycle suit. Excellent quality as you would expect from the Italian manufacturer.  It is used but in very nice condition, it does show signs of wear but only what you would expect from a used suit.  Its has never been damaged or repaired and I have never fallen in it. I paid over a thousand $ for it about 4 years ago. Its not a common design as I purchased it on a visit to the UK.
It is a Euro size 50.
Regarding size the following may help-
  Dainese say- Chest 40" to 41"    Waist 34" to 35"   Hip 36" to 38"     Height 5'-8" to 5'-10"
I am 41 chest 5'-10" and weigh 165 lbs and its a good fit, I can get a back protector in if needed.
Thanks for looking
