Having spent a lot of time over the years trying to improve my French, I have found a favorite source for new terms is fashion magazines. Luckily, I am a Fashion Fiend along with being a fashion illustrator, so this is not a problem (and the expense is deductible!)
A stiletto (or "stillie" as a friend of mine calls them) is a fashion classic, albeit murderous to the health of the human foot. No matter, un talon aiguille is a staple on the pages of Vogue as well as holding pride of place in many sophisticated closets. The term is apropos in French, as une aiguille is a needle.
Some silly girls have been known to spend their rent money on a pair of "Loubous" (not me! not lately, anyway...)
