Wow them in a strapless tuxedo jumpsuit like Khloe

We know Khloe Kardashian loves a good jumpsuit. The former talk show host has worn a number of high end versions from Balmain to Roberto Cavalli to Prabal Gurung and the list goes on! Here she chose a one-piece by Ralph Lauren during her trip to San Diego to visit her grandmother, MJ.

It's a rare occasion that a Kardashian wears the same outfit twice, but Khloe wore this silk stunner back in March with a House of CB duster coat to an event in NYC and she looked just as good then as she does now!

True to Ralph Lauren's classic signature style, the jumpsuit had a strapless silhouette, wide-leg pants and a tuxedo stripe along the sides. Khloe wisely chose a simple pair of black pointy toe pumps to finish off the look.

Voluminous black lashes and minimal jewellery completed the outfit, which let her stunning slimline figure take centre stage.

She added a bright yellow Birkin and pointed heels as she joined sister Kim and half-sister Kendall Jenner.

Kendall carried her niece North, while Kim teetered in wearing tiny strappy heels and a sand-coloured shirt-dress, as the family headed to the races at the Del Mar horse-track, to celebrate with Kris Jenner's mother MJ.

Khloe shared a Snapchat from the glamorous day out, her giant dark glasses making her look even more glamorous. 

Kendall wore an off-the-shoulder white top, with a black scarf knotted around her neck to give a continental feel.  

Scott Disick - her sister Kendall's ex and father of their three children - made sure he was unmissable in a maroon and pink rose print jacket which would not have been out of place as a pair of curtains.

Khloe is known to get in a rigorous workout on a regular basis, after previously describing herself as being the 'fat one' in her family while growing up.  

The reality star admitted to straying away from her usual healthy routine when she tweeted out on Tuesday night, 'I had no self control eating wise today lol. Not cute!' 

She added: 'Road trips + birthday cake + no workout = disaster.'

In her 2015 book, Strong Looks Better Naked, Khloe wrote that the secret to weight loss is lifestyle change, not dieting. 

'When you diet, you are basically setting yourself up for failure,' Khloe said. 'I mean, the word die is in there!  

'You’re not allowing yourself to enjoy the food you love, and it will only make you want it that much more.

'Make smart lifestyle changes, one baby step at a time,' she advised.
