If you've had enough of the risque sideboob trend, you might want to look away now.

Daring fashion has gone to new heights with a trend known as a "sideflank".

The extra revealing take usually involves a flash of "sideboob" or "underboob" mixed with a super thigh-high split — and there's definitely no undies allowed.

From lace inserts to cut-out dresses and crochet designs, dozens of stars are flashing their legs in the racy new style trend.

And they don't need to be on a beach to embrace it, you can find it everywhere from the red carpet to Instagram shots from fancy restaurants.

The likes of Kendall Jenner kicked things off back in February with her extreme take on a "naked" dress. The couture designer Rami Kadi's outfit featured a long length skirt at the front and back, but was missing any sides — meaning her long pins were on full display from the waist down.

Australian mega-influencer Tammy Hembrow is also a fan of the bold look, choosing to take hers to extra heights with a see-through crochet design, but it was Jennifer Lopez who took it to the max.

Kate Moss' daughter, Lottie Moss and Sofia Ritchie, have also got involved — rocking various side-flashing ensembles on the red carpet, proving nearly-naked dresses are back but this time on steroids.

Just this week American YouTube star-turned-singing-sensation Madison Beer turned heads in a very racy white dress. The 20-year-old showed off a serious amount of flesh while attending the TrevorLive charity gala in Beverly Hills on Sunday night, giving onlookers a cheeky flash of sideboob.

But it was the Grecian-inspired gown's racy thigh slit that caught everyone's attention thanks to its super daring cut that appeared to go as high as her midriff.

As Madison posed in the unique dress — which was also made from a see-through material — her left leg was on full display, talk about rocking the "sideflank" look.

If you want to try this for yourself, you'll probably need a lot of "boob tape" — but we suspect it could be one best left to the supermodels.
