I found this, from Fashionista.

Here’s the money quote:
Historians believe that, at first, tulle was painstakingly woven by hand using methods similar to lace production starting around the 1700s. Modern-day tulle (also known as bobbinet) was first produced after a complex weaving machine that could efficiently produce the fabric was patented in 1809. [1] After that, tulle became integral to high-end wedding gowns, evening dresses and lingerie. Once a prohibitively expensive and luxurious textile made of silk, tulle eventually became readily available to the masses thanks to the introduction of cheaper synthetic fibers such as nylon, rayon and polyester.
If I decide to get something tulle, I’m glad to know there are versions made of renewable fibers rayon and silk. Wonder how expensive they are?
And a possible explanation of why it’s popular now
While the tutu has historically symbolized discipline, purity and beauty (for the sake of the male gaze), wearing a tutu-esque skirt alongside, say, combat boots and fishnet tights subverts the garment’s original connotation and makes a statement against the values it traditionally represented. Some theorists have also noted that embracing the tutu look serves as a way for a woman to communicate her power and individuality without sacrificing her desire to embrace her "girlish femininity," an ephemeral quality that women are told to give up in order to become respectable wives and mothers.
Sounds good to me! I think we often are attracted to a look partially because of values attached to it that we might not realize on a conscious level.
