A bit over a year ago I stopped wearing a tie to work, mostly because nobody else at work wears a tie.
When you wear ties, they can be the distinguishing feature in your work attire. When the tie is gone, it’s harder to get away with, for instance, wearing white shirts every day.
So I’ve bought a bunch of different coloured/striped/checked shirts. Stocktake sale time is a good time to stock up. Van Heusen do quite a nice “European” cut, which is a bit slimmer than their normal “classic” slobby look, but not so slim every belly bulge shows.
I’ve got mostly blues, I have to admit, though recently I’ve branched into a few other colours; for instance a couple of hopefully-not-too-dull greys, one in lavender, one that is white with stripes of pink and a couple of other colours. Groovy.
