I've been down the compromising route, not one person is willing to even talk about it anymore.Can't you compromise somewhat here? You get to close the windows behind/near you and they wear a bit less into the office - still maintaining decorum (or not, as they choose).
I tend to suffer the opposite problem to you though, I'm almost invariably too warm in any office I've worked in so while I'm down to short sleeves and visibly overheating the rest of the office is complaining of the chill.
As for office decorum, it's anybody's game as far as what you want to wear here. One of the directors wears shorts, tshirt and wanders round bare footed. All year round :/.
Obviously for me it isn't.At least its not too bloody hot, thats way worse
