In England a vest is an undershirt. Here in the States a vest is the piece of clothing you wear buttoned up over your dress shirt. I own a few vests but rarely wear them. My wife thinks vests are HOT but I think vests are just hot. It’s too hot to wear a vest and a jacket to any special occasion for my taste and wearing a vest with short sleeves is just wrong. I found my vests when I was looking for my cycling jacket and wondered if I would ever wear another vest and not look like a Mumford & Son. I do still like the look of my tweed vest with the pockets and brass buttons. I still have my old tweedy irish hat. It is Fall. Is it wrong to wear a vest with jeans? Could I pull it off? Am I too old? Wish me luck. I think I will don on a vest and try to make it look polished and elegant for a change. I feel the need to let you know it’s not a sweater vest, but a proper tweed vest…I do not know why I have that need to point that detail out to you. Perhaps, it was the years in private school wearing sweater vests and braided leather belts with boat shoes.
