According to Kourtney Kardashian, underboob is the new sideboob

WHILE Kim Kardashian made headlines for her unairbrushed backside yesterday, her sister Kourtney had another body part on show.

IF THE KARDASHIANS are good at one thing it’s having body parts spilling out of teeny-tiny bikinis.

And pants. And tops. Come to think of it, they’re not discerning. They’ll spill out of anything.

While everyone was marvelling at Kim’s unairbrushed derrière waving at us all from the sides of a black G-string yesterday, another Kardashian had a different body part on parade.

Kourtney Kardashian Snap-chatted a picture of herself reclining while on a birthday holiday in Mexico. Spilling from underneath her tiny red bikini — like a cheeky puppy peeking out from underneath a doona — is more than a hint of underboob.

As such, gossip mags today are littered with headlines like “Kourtney Kardashian is trying really hard to make bikini underboob a thing”.

It’s odd that such a trendsetter is spruiking the look of an ill-fitting bikini — the same look that many of us sported as teenagers, which caused our mothers to march us off to the gruff bra-fitting specialists at David Jones.

Some people were debating whether the picture showed a simple wardrobe malfunction — we’ve all had a pesky bikini top that has ridden up.

But the label’s Instagram would suggest the bikini has been designed to be worn that way.

And let’s face it ... the Kardashian’s rarely do anything accidentally.

The other proof that underboob is Kourtney’s look de jour is the fact that she posted two other pics to Snapchat.

She’s having a “siesta” in this photo in case you were wondering.

And here you go! Another one for the people in the cheap seats:

The reaction to the look on social media was fairly positive.

The bad news for Kourtney is that she can’t lay claims to be the Underboob Pioneer (TM).

People like Kelly LeBrock had it going on way back in the ‘80s:

Kelly LeBrock ... giving some solid underboob.

So what’s behind this new impractical and undoubtably uncomfortable new fashion trend? Probably a new Kardashian swimwear line.

Also, it will be interesting to see who draws the short straw and has to tell Kim that sideboob is so last season.
