Beautiful vintage bespoke waistcoat for gentleman's evening wear, in excellent condition.  Made in England in 1957 by Denman & Goddard, for R T Combe (later Captain Combe of the Coldstream Guards).
The front panels are white Marcella (pique cotton).  Two pockets.  Adjuster band at the back with toothed buckle marked PARIS SOLIDE.   Needs to be worn with 3 detachable waistcoat buttons/studs (not supplied, available separately).  
Size (not marked in garment, taken from measurements):
Chest 40".
Length, shoulder to points at the front 20" (this is a LONG waistcoat for the 1950s, and was made for a tall gentleman).
Width of front: 17.5".

Condition: Well over half a century old, but in superb condition.  It has been recently cleaned (but not starched).  There are some rust spots on the backstraps, presumably where the waistcoat was once stored with a rusty buckle - this will obviously not show when you are wearing a jacket.  (The present buckle is a replacement.)  Original owner's laundry mark inside.
