Take a look at this video from new comedy website MarcherLord.com. You will be pleased to hear the the gentlemen’s clothing is all period correct (i.e. it is all from the 1930s) and was supplied by us!
The butler is wearing a 1938 Austin Reed morning coat and 1923 JB Johnstone & Co. cashmere striped trousers and black waistcoat.
The particularly striking actor at the bridge table is wearing a 1930s Montague Burton dinner suit (with M&S shirt and bow tie unfortunately) whilst the over-actor at the fire place is also wearing a 1930s Montague Burton dinner suit (with Ede & Ravenscroft bow tie I think).
