If the cap fits if the cap fits, wear it has been around since at least the early 18th century, and is probably older. A work of 1600 called pasquil's fools-cap with the passage 'where you finde a head fit for this cappe, either bestowe it upon him in charity, or send him where he may have them for his money' suggests that the expression was known then, and also reminds us that the cap to be worn is a dunce's cap. In america, this saying is more likely to be found in the form 'if the shoe fits' or even, perhaps under the influence of the cinderella story, 'if the slipper fits'
