Khloé Kardashian flashes her bra on a girls' night out with sister Kourtney... as they run into with her ex French Montana at LA hotspot

Kourtney and Khloé Kardashian donned black outfits and matching thigh-high suede boots at West Hollywood hotspot The Nice Guy on Friday night.

The Keeping Up with the Kardashians siblings partied alongside an entourage of gal pals, which may or may not have included Khloe's ex-boyfriend French Montana.

The 31-year-old reality star has been rocking the same plaited hairstyle since Wednesday and flashed her bra with the daring ensemble.

Khloé dressed her 5ft10in figure in an ultra-sheer top, which showcased her lacy bra.

The Strong Looks Better Naked author finished off her club look with massive hoop earrings, a faux fur coat, and skinny jeans.

She and French, who split in 2014 after two years of on and off, have not been spotted at the same venue since a concert by The Weeknd in December last year. 

The blonde presenter currently hosts an adult-themed, eight-episode talk show Kocktails with Khloé, which airs Wednesdays on the FYI network.

Walk tall in Kourtney Kardashian's thigh high boots

Originally famed for her more laid back styling, Kourtney Kardashian has been championing an altogether more, well, Kardashian look of late.

It's perhaps work of super stylist Monica Rose, who has a penchant for dressing her clients in a combo of high hemlines, structured tops, mega-watt accessories and her latest obsession: thigh high boots.

And it seemed Kourtney certainly fit the Monica Rose mold as she stepped out on Friday, looking on fleek in a black knit, fringed mini skirt and velvet boots by Aquazzura.

Thigh high boots have made waves as the footwear choice du jour, and are more wearable than you might think; the trick is to balance the fierce look with more relaxed pieces such as slouchy shirt dresses and knitwear.

This week it featured the revelation that she once walked in on 'an ex' as he was joined by two companions in the bedroom.

In a new video, the 31-year-old tells hairstylist Jen Atkin and make-up artist Hrush Achemyan: 'One time I walked in on my current boyfriend at the time, he was having not just sex, a threesome, with two girls that he met at the mall earlier that day.' 

Her 36-year-old sister Kourtney also had exes on the mind as the single mother-of-three tweeted a retro snap of her babydaddy, Scott Disick on Flashback Friday. 

The on/off couple appear to be back together for the sake of their son Mason, 6, daughter Penelope, 3, and son Reign, 13 month.

For her girls' night out, she shook things up in a fringed mini-skirt, which she paired with a clingy turtleneck.
