Irvin sizing query

[Dan0099]

Good evening all, I'm a new member, but a long time viewer.
Been in the market for an Irvin jacket for a while now. Have bought some, but haven't kept them as I've being pretty unsuccessful with fit.
My aim is to wear on the motorbike on those colder mornings and also when going for a winter stroll.
Don't really have the funds to buy something new at £1000+ and don't want to buy a mall jacket.
Would someone mind having a look at the attached images to see what sort of size Irvin this is please? It doesn't have a size label on the jacket.
I'm a 46-48 chest, hoping for something that is a bit more fitted than something that makes me look like the Michelin man.
Any help would be greatly appreciated.

Suggest Always taking chest/gut/shoulder measurements with Fully inflated chest. You might find that "upsizing" will be a distinct comfort advantage.

Also strongly suggest that wearing the Irvin jacket with the collar raised will impede your peripheral vision on the bike. RAF fighter pilots apparently shunned the Irvin after a while since parachute and seat harness straps forced the user to raise the collar. There are reports of fighter pilots cutting off the Irvin collar. Bomber aircrew, not being in same situation, stayed with the Irvin.

Hello, apologies for the late reply. After much searching, I ended up getting the Goldtop Battle of Britain. It's really nice and the fit is lovely, it's a bit more fitted than the Irvin's. If there is anyone wanting some photos or a review, I'd be happy to post one separately.
