I am selling a coat with no size. How do and where do I measure for chest measurements please

[Bananaknickers]

haven't a clue and someone has asked me. The only information I have is that is a medium.

button it up, lay it flat on the bed and measure from armpit to armpit. Tell the enquirer this is what you did.

Mrs badger thank you so much will do that

also i use an old mail order catalogue (freemans etc) to match the measurements i take myself to an actual uk size, as it helps if you can put the size in the listing title.
