Hello all. I've been reading back through the last 30 or so pages of this thread and it's a great resource, thanks!
I'm looking at a vintage pea coat listed on e-bay, here: http://www.ebay.co.uk/itm/Vtg-Black-US-NAVY-Military-Wool-Winter-PEA-COAT-38-Medium-/281047583466?pt=UK_Men_s_Coats_Jackets&hash=item416fbdcaea
The measurements (as far as they can be relied on) look pretty good for me, I'm right between a 39/40" chest so a 22" p2p should be good, and I'm 6ft 3 so I need a reasonably long arm.
Would be interested in any feedback on the coat itself. There's no date there, but having read through Peacoat's guide to dating, I guess it's a fairly recent one based on the colour (black) and type of wool. I don't recognise the label from that guide though, so I thought I'd check just in case. The other pea coats listed seem genuine enough, though the dates are usually a decade or two out judging by their labels! The user has excellent feedback, at least.
The p2p is 21" which will fit like a size 40.
You can't depend on the seller to give the color accurately. Inside, the vintage pea coats look black, but are actually a deep midnight blue. One has to take the coat outside before the true color is observable.
See if she can find a tag on the coat. She can try the vest pocket--either inside or outside, or, as svart asks said, one of the hand warmer pockets.
The 25.5" sleeves don't seem as though they will be long enough for some who is 6'3". However, there probably is enough material inside the cuff so the sleeves can be let out an inch or so.
