If you thought North West was the only Kardashian grandkid with an ultra-luxe wardrobe, you'd be wrong.

Penelope Disick was spotted out and about in Los Angeles this week, toting her very own Hermès Baby Birkin bag.

Emphasis on the word 'baby,' because little Penelope is only three.

The youngster was accompanying her mum Kourtney Kardashian and baby brother Reign on some errands, and was working some serious outfit co-ordination in her black and pink ensemble.

At €7,500 a pop, it's unlikely Penelope bought her new bag with pocket money, but given her grandma Kris's obsession with Baby Birkins it could well have been a Christmas present from her.

The Kardashian momager took to Instagram last year to tell fans how much she loved the mini versions of the hugely popular Hermès design.

Of course, it's not only Penelope who was working some high-end fashion on the family outing – Kourtney's black-lace up St. Laurent ankle boots retail at a cool €830.

Quite the mum-and-daughter fashion duo.
