Now, usually, dressing twins alike after the toddler years is considered a tad strange, casting up visions of middle-aged siblings in identical jumpers riding a tandem bike and waving in unison at passersby.
But in the case of stylish twosome Hailie and Brighton Ehat, we'll have to make an exception.
The six-year-old twin sisters have gained a huge and well-earned following on Instagram with their matching intricately done hair dos. Thanks to talented mum Jill, the sisters' detailed dos are like looking in a mirror.
Jill, who is also mother to eight-year-old Cole (who, unsurprisingly, doesn't seem interested in having his hair braided), has been dressing people's hair for as long as she can remember, first on her own sisters, and then on school and university friends.
So when she had two daughters of her own, it was only natural that she continue to work her magic on her two new models. Since she started uploading photos of her complicated creations to Instagram last year, her account has won over 60,000 followers.
The hairstyles she tries out with the girls, including Dutch braids, rope twists and 'fauxhawk braids', are designed to be practical as well as pretty, Jill explains in a blog post.
"I'm especially good at tighter braids and active styles because my girls have something nearly every day like dance, swim, tumbling or soccer."
Their favourite thing at the moment, Jill explains, is 'twinning', which is when an Instagram user poses with the same clothing or hairstyle as a 'twin' on the site, who may be on the other side of the world.
And the fashionable pair are already learning the ropes for themselves. Jill says they are always eager to practise braiding and ponytails on anyone who will sit still long enough to let them. Like mother, like daughter!
