Between two sizes? Size up. The waistcoat is cut long over the belly, so sizing up adds room through the middle and the back strap pulls in the waist. Measure your chest by wrapping a soft tape around the fullest part, under the arms, level and snug but not tight. Sizes S through 5XL.

“I'm 58. I've owned four blazers in my life and hated all of them. Hot, stiff, and I always looked like I was trying too hard. Put the Lancaster on over a white shirt for my daughter's engagement dinner and that was the whole outfit. Belly stayed put. Nobody missed the jacket. I didn't either.”
Dave K.Customer experience“I want to be honest about what this does and doesn't do. It doesn't make you thin. What it does is stop your shirt from wrapping round your gut like cling film. The front is stiff enough to hang straight, the waist is cut in, and from the side I look about ten pounds lighter. That's it. That's why I bought three.”
Steve B.Customer experience“My wife had to remind me to take it off when we got home. That's never happened with anything I've worn to a wedding. Eight hours, a hot marquee, dancing, and it just sat there breathing. I've sweated through a shirt at every summer do for a decade. Not this one.”
Alan W.Customer experience“Big up top, soft in the middle, and everything fitted showed it. This is the first thing that smooths over my chest and the rolls at my sides without squeezing. It actually gives my chest a line. Lad at the bar asked if I'd started lifting. I have not started lifting.”
Tony G.Customer experience“Do you know how many 'big and tall' waistcoats stop at 3XL and then ride up like a bib? All of them. This goes to 5XL, it's cut long so it covers my stomach, and there's a strap on the back that lets me pull the waist in properly. First waistcoat I've owned that sits flat and stays flat.”
Marcus L.Customer experience“Twenty years married and she'd stopped commenting on what I wore. Fair enough, it was the same polo every time. Wore the burgundy one out for her birthday and she said I looked like the man she met. I'll be honest, I bought this for the belly. I kept it for that.”
Paul H.Customer experienceHere is what people want to know before they order.
It won't make you thinner, and we won't tell you it does. What it does is stop your shirt from clinging to your gut. The front is structured to fall dead straight over your stomach, the waist is tapered, and the stretch fabric smooths your chest and sides. 87% of guys say they look more buff the second it's on.
No. That's the whole reason it exists. Bigger guys have always had two options: a shirt that clings, or a jacket that's stiff, hot, and feels overdressed. The Lancaster is the third one. Over a shirt it's the finished look on its own.
Sizes run S to 5XL. It's cut longer through the body so it covers your stomach instead of riding up, and there's an adjustable strap on the back to pull the waist in. If you're between sizes, size up.
Wear it for 30 days. Take it to dinner, a wedding, a night out. If you're not in love with it, send it back for a full refund. Exchanges for size are free within the 30 days.
