Jennifer Lopez just invented the 'naked jumpsuit'.

The “naked dress” has become a mainstay of red carpet fashion. Featuring flesh-baring cut outs and plunging-to-the-point-of-concerning necklines and splits, it’s been spotted on just about everyone from Beyonce to Jesinta Campbell, with a fair few Kardashians in between.

Now Jennifer Lopez has just trumped them all.

Celebrating her 47th birthday with a sold-out performance and exclusive VIP after-party attended by the likes of Kim Kardashian and Calvin Harris, Lopez took the concept one step further with a new invention. Behold, the “naked jumpsuit”.

Rocking a Balmain number specially customised for her, Lopez gives a whole new meaning to the term birthday suit.

Not only does she look incredible, she’s also managed to give a trend, that was steadily losing its shock factor, a new twist. (Post continues after gallery.)

We’re talking completely sheer sides and back with a few thin chocolate brown panels of modesty. The essential accessory to a piece like this? Confidence — something Lopez had in spades.

After her official performance on stage, the Jenny from the Block singer did an impromptu dance and a 360-degree show of the jumpsuit on Snapchat with Calvin Harris.

You can bet that there are no granny undies going on here...

While just as risque-looking, the "naked jumpsuit" does have some serious advantages over its free-flowing cousin.

There's no up-skirt situation to worry about and your, erm, private parts are much better guarded should a rogue gust of wind blow your way.

You can perform on stage like Lopez, dance or even cartwheel to your heart's content, knowing everything is safe and contained.

Bring on J-Lo's 48th celebrations.
