Gigi Hadid's birthday party dress code was double denim and we cannot get enough of it
Updated: May 29
Spoiler: Bella opted for TRIPLE denim.
It's the question that divides the nation: Should you or shouldn't you double up on your denim?
Here at GLAMOUR, we're of the firm opinion that twice the denim = twice as good.
And if Gigi Hadid's 24th birthday party is anything to go by, its a look that's only growing in popularity.

Scroll down from some serious inspiration, from some of the chicest celebrities styling the look...

Katie Holmes works the perfect look for those who are new to double denim: team your denim jacket with grey or black jeans and you will feel less like you are wearing a Canadian tuxedo but will feel effortlessly cool. Also big plus points to Katie for the Adidas Stan Smith shoes.
Reese is working a slightly more polished version here with her black skinny jeans and blue denim shirt. Add a slick of pink or red lipstick and you're good to go.
Kate Bosworth wears different shades of blue to great effect.
If a look works, why not wear different versions of it? ‘Repeat offender’ Bosworth looks super cool. We're a little bit jealous of the chunky silver necklaces and that awesome dip dye shirt.
J-Lo works her typical high octane glamour with figure-fitting denim shirt and jeans, aviator shades and stacks of silver jewellery. Very nice.

To be fair, Miranda Kerr would look amazing if she wore a hessian sack but we are so totally in love with this classic denim shirt and jeans ensemble; and leopard print works a treat with blue jeans.

Chloe Sevigny can do no wrong in our books and she looks her usual cool in the hot Coachella dessert in this chic denim ensemble.
Here's a tip: A trend is not a trend worth pursuing if it hasn’t been worn by Alexa Chung at some point. However, Pixie is no slouch in the style stakes, she's working Madonna circa 1987 and that can only be a good thing.
Although we're not entirely convinced by Pixie’s footwear, we adore her double denim co-ord suit.
How awesome does Olivia Palermo look here? If you're not rushing out to buy a denim skirt right now, then double denim might really not be the right thing for you.
If Olivia’s outfit is a bit too Upper East Side New York for you, then Rihanna’s bad ass take on the look might be more your thing.
The denim waistcoat might not be everyone’s cup of tea but it has a very firm place in the history of rock music attire; that’s why we applaud Kristen for giving it a whirl.
Who better to demonstrate this than our very own Status Quo. Would you ever guess that they had a sponsorship with Levi’s at the time?!
Another rock staple is the cut-off denim jacket and Brian Johnson of AC/DC is working a particularly fine 80s number here.
How could we discuss music and denim and not mention Debbie Harry? Her ice queen look in the late 70s pretty much set the blueprint for every front woman in a band ever since.
It’s Elvis! *faints*
Speaking of cool dudes, Robert Redford casually striding down the street in 1976 is totally nailing that look.
In the same year, Charlie’s Angels chain themselves up and wear matching denim shirts and flare jeans. What's not to love?
The 70s were really a vintage decade for denim and we just have to include this awesome picture of Susan George and Peter Fonda in 1974 in Dirty Mary Crazy Larry.
Here's Robert Redford (again) in the romantic western The Electric Horseman. He plays a (hot) cowboy. Enough said.
Drew Barrymore working denim the grunge way in 1991. This outfit has 'cool' written all over it.
