CELEBRATING THE RUFFLE
No way are all ruffles standard. Because there are so many different kinds, a whole book could be written in praise of them. As you've probably figured out from the above photo, ruffles can be worn head to toe on bodice, sleeve, skirt or train. And don't forget those accessories. I've seen shoes, purses, gloves, hats and veils layered in ruffles. Below are just a few treatments, mostly skirts, celebrating the ruffle.

Above is not a ruffle so much as pick-up or bustling effect creating a lower ruffle as bustling does.

Most ruffles run horizontally; the ones on the Sarah Houston gown above fall vertically instead creating a cascading kind of waterfall effect.
Christian LacroixLooks like Lacroix innovated some sort of ribbon ruffle above. That's what geniuses do . . .

These skirts by Joan Shum and Max Chaoul have ruching treatments. Ruching is one form of ruffling. The ruffle is typically center gathered rather than top gathered. Many gowns in the 1930s era had ruched sleeves, skirts and trains.

Denise FrigerioThe photos above and below have pleated ruffles. Generally pleateds are made out of light, crisp fabrics like organza and have lettuce hemlines, producing that Fortunyesque pleat effect.

The bias cut ruffles above are not gathered up top to create a pouffy effect. Instead they're typically cut in a circular pattern on the bias so they fall gently. Many gowns from the 1930s are famous for their layers of bias cut ruffles
