If you're a fan of the Haute Couture shows, you'll be familiar with tulle - the couturier's fabric of choice for creating princess gowns.
But this Autumn/Winter season, expect to see a whole lot more on the streets because tulle has gone mainstream.
We have young British designers including Simone Rocha and Molly Goddard to thank for tulles trickle down onto the high street.
In just three short seasons, Goddard has made a name for herself as the maker of the sorts of fairytale dresses you would have thrown a tantrum for when you were little; Frothy, ruffled and beautifully nostalgic, but mixed with a cool-kid vibe.
But erase all images of sashaying around Sainsbury's in a red carpet-worthy gown (although who wouldn't want to do that?), tulle is to be considered a layering tool, added over jeans, trousers or slip dresses, under oversized knitwear and shorter-length skirts.
Think of it as an easy, fuss-free way to add interest to even the most simple of outfits, like jeans and a T-shirt.
Zara has, of course, already got tons of tulle on offer (we're predicting this dress will be a sell-out), while ASOS has some serious must-haves coming in its Christmas drop, available from the end of October.
