Mariah Carey demonstrates how to dress like a diva

To celebrate we’ve had a look back through Mariah’s wardrobe over the years.

The diva is in the detail.

To mark her arrival at Caesars Palace in Sin City, Mariah was driven down the strip in pink vintage car before stepping out to reveal this nude gown, twinkling with gold dust in all the right places.

For the opening night of the show, Mariah had her hair teased to perfection, with a barnet so big it almost rivalled her vocal capacity. Sequins and lots of cleavage are must-haves for a diva on stage.

A diva’s allowed to be temperamental when it comes to her moods, and Mariah is both cool as ice and smoking hot in this blue gown.

There was a twist to this elaborate stage outfit when Mariah performed in Vegas back in 2009. When she climbed out of the swing, she also left the enormous skirt behind to reveal a teeny mini-dress underneath.

In her forties (no one know’s Mariah’s real age) and two years after having twins, Mariah shows off her midriff at an event in 2013.

When Mariah injured her arm she wasn’t going to step out in public in just any old plaster cast. So she opted for this studded, leather number to match her outfit.

There is an old fashion rule that says you should choose between flaunting your legs or your cleavage. But Mariah doesn’t obey any laws but her own, and loves a tight mini with a plunging neckline.

This outfit has everything golden girl Mariah loves – sparkle, frills, and plenty of flesh on show.

Performing at a summer concert Mariah goes for casual beachwear – if you are the kind of person who can wear pristine white hotpants to the beach and not get a speck of sand on them.

Some people use optical illusion prints to try and play down their curves. Mariah uses them to ramp hers up to full effect.

Who needs clothes when you’re performing in front of millions of people?

When divas do casual. This is what Mariah wears to go shopping.

When Mariah can’t choose between a mini or a floor length gown, her wardrobe department have to think outside the box.

Throwing the first pitch at a baseball game in Japan, of course Mariah would have her own personalised pink jacket.

Being five months pregnant would never come between Mariah and a sparkly frock.

Here’s Mariah’s take on the “just got out of bed” look when she appeared on Good Morning America in 2013.

Mariah just throws on some jeans, oh and a bejewelled butterfly bra.

Accessories are very important to getting an outfit right. Like strips of material that float around you when you wave your arms in the air.

There’s a reason why you should coordinate your underwear with every outfit.

Mariah made sure all eyes were on her when she attended the Oscars with then husband Nick Cannon.
