I have here a plain Navy SuitSupply suit in the Washington fit. Suit has been worn once for a wedding and has been sitting in my cupboard since so it's still brand new.
The size is 40S or in SuitSupply, it is referred to as Size 25. The measurements are available on the website.
Jacket has not been altered in any way. Trousers have been hemmed to 39.5 inches with a 1.5 inch cuff.
Letting it go for 300USD. RRP is 499 so you're getting a pretty good deal. Will ship internationally with tracking number included. No low ball offers please.
