Do I know any size 42 gents? If I did or if I remembered you would have received a message from me about this amazing 1930’s suit, labeled “Paramount Wardrobe” as in this suit was made for the movies! I’m just going to copy/paste the seller’s description because this suit is so rad:
“Original Men’s 1930’s two piece BACK BELT SUIT in Size 42” chest in a nice medium cocoa brown wool flannel suiting. The jacket is single breasted with two lower patch pockets and decorative seams down the front. The back is pleated into a half belt and has a “Bi-Swing” action back with two long vertical pleats. The pants have a pleated front and two side and two back pockets. The only markings are an ink stamp on the trouser waistband: “Paramount Wardrobe”
The suit measures:
Across the shoulders: 19″
Down back from collar seam to hem: 31″
Sleeve from shoulder seam to cuff: 24 1/2″
Pants waist: 36″ (can be let out to 38 1/2″
Pants inseam: 31″ (can be let out to 33 1/2″)
There are no rips, tears, stains or mothing, etc on this suit. It’s in excellent condition.” (Emphasis added.)
42 gentlemen, it is your imperative and your directive that you acquire this suit – go forth and conquer!
