The new Kensington shoes by American Duchess. Which you can win in a giveaway here, together with Courage, a series about a fictional 18th century American town. I have never heard of the series before, but it sounds intriguing.
I like the Kensingtons even a bit more than the Devonshires. They're more of my kind of shoe, somehow. The difference is subtle, but it's all the difference in the world... They're narrower. I have narrow feet but high in the arch (which proved to be a big problem years ago when buying sport shoes), so narrower latchet shoes sound like exactly my thing. Although they're not quite my kind of colours at the moment.
And as someone pointed out, these could actually work for Edwardian or 1930s style as well. I did not see latchet shoes in the 1930s magazines I have at hand (more tomorrow), but I agree that the shape looks similar. I like versatile things.
