VATPAVEMens Victorian Suit Vest Steampunk Gothic Waistcoat

I have a 44 in chest and a 32 in waist. What do you recommend?

Normally the small starts at 38 not 40, like this https://www.amazon.com/darcchic-double-breasted-waistcoat-aristocrat-steampunk/dp/b079l5m3h1/ ?

I am 6’1 and weigh 210 what size?

I'm looking to buy, I'm 5'4" and 3/4 at 250 lbs and my gut sticks out more than I am wide. Any suggestions on size?
