Suit jacket has no size label - how do I find out chest size?

[pumpkinpillow]

I want to sell a suit on Vinted. The trousers have the measurement, but not the jacket. It no longer fits the person it was bought for so I can't measure him.
Does anyone know what measurement on the actual jacket corresponds to what chest size?

I got it from Suit Direct last year, I have no idea why it has no size label.

Have you looked for any labels inside the inside jacket pockets? I worked in men’s retail for years and they were often in there.
When you bought the suit was it sold as a fixed set? If it was a fixed suit (ie the jacket and trousers were already paired up) then generally there is a 6” drop between the jacket chest size and the trouser waist size. So if the waist of the trousers is 34”, then the jacket would be 40” - however it wouldn’t measure that if you laid it down flat (it would measure a bit bigger).

Ah thanks. I had looked, but not in all of them! Found it!

I would never have thought there were two such interesting revelations about men’s suit jacket measurements!
