Perhaps she's congratulating herself on a bargain.
For big sister Kim was seen deciding to part with the very same bag in an episode of Keeping Up With The Kardashians screened last August.
And with what appear to be Kim's Givenchy's $1,695 Shark Lock fold over wedge boots on her feet, Khloe had apparently scored a designer outfit for free.
Thifty! Khloe Kardashian carried Kim's fur-lined Louis Vuitton bag and wore her $1,695 Givenchy boots as she arrived at LAX for a flight on Wednesday
Looking stylish: The boots looked much better on Khloe, who is several inches taller than her petite sisterKim was first seen wearing the eye-catching boots when she visited Hawaii with Kanye in August.
But perhaps she decided they weren't to her taste after all.
It was a different case when it came to her Louis Vuitton bag.
Then Kim was seen trying to persuade her boyfriend to allow her to keep it allowing him to give her closet a makeover.
Proud of her bag: Khloe is not above accepting her sister's hand-me-downs
But Kim didn't give up.
'Shouldn't I just keep this for, like, my daughter one day?' she asked Kanye.
Cringingly he failed to appreciate her hints that they might one day have a family, instead remaining pointedly silent.

Not impressed: Kanye disliked the bag, but Kim wanted to keep it for a future daughter to inherit
Of course his reticence was just for show - as a few short months later Kim is now pregnant with their first child.
And it seems she was also pretending when she agreed to get rid of the bag - which she appears to have thriftily handed onto her little sister.
Strong-willed Khloe certainly didn't seem put off by the 'dog's bag' comment, rocking the bag with a slick of red lipstick and a warm sweater as she arrived for her flight at LAX on Wednesday.
