The Secret Life of Syrian Lingerie -- The most outrageous and exuberant lingerie in the world comes from a place you’d probably never expect: Syria. Adorned with everything from faux fur, artificial flowers, and feathered birds to plastic toy cell phones, these intimates flash lights, play music, even vibrate. Well known across the Middle East—in Syria the lingerie forms an important part of the folk tradition around trousseaus and weddings—it is openly displayed in the markets and souks.

As Sadie Stein aptly observes, the thesis is even more interesting:

The authors find that the more religious the area — and correspondingly, conservative women's outerwear — "the more risqué the underwear."
