Fashionable Contrasts;—or—The Duchess's little Shoe yeilding [sic] to the Magnitude of the Duke's Foot is a print by James Gillray.
As well as being blatant in his observations, Gillray could be incredibly subtle, and puncture vanity with a remarkably deft approach. The outstanding example of this is his print Fashionable Contrasts. This was a devastating image aimed at the ridiculous sycophancy directed by the press towards Frederica Charlotte Ulrica, Duchess of York, and the supposed daintiness of her feet. The print showed only the feet and ankles of the Duke and Duchess of York, in an obviously copulatory position, with the Duke's feet enlarged and the Duchess's feet drawn very small. This print silenced forever the sycophancy of the press regarding the union of the Duke and Duchess.
