Warning: Spoilers ahead for “Game of Thrones” season seven.

One of the best parts of “Game of Thrones” season seven has been the dark new costumes nearly every character is wearing. INSIDER caught up with the HBO series’ costume designer, Michele Clapton, to learn more about the new looks and what they mean for each character.

“I love the details,” Clapton told INSIDER. “Some people say, ‘Well, why don’t you make it more obvious,’ but that’s the joy of ‘Game of Thrones’ — you have to search things out.”

Let’s take a closer look at the main character’s new costumes this season.

We first saw Daenerys Targaryen's new look in an HBO promo. Her fur-lined coat and new dragon chain were front and center.

Ahead of the season seven premiere, HBO aired a promo starring the 'Game of Thrones' cast. Each of them mimicked the iconic HBO 'ahhhh' noise, hence their open mouths.

But this was a fantastic first look at Daenerys' new Dragon Queen look.

'She now has this fantastic new chain we've created,' Clapton told INSIDER. 'I didn't want her to have a crown, I wanted her to have a chain. And she has a red sash hanging from it, which is slightly scaled and pleated as well.'

The new wide shoulders and red detailing is meant to echo her brother Viserys.

Viserys was Daenerys' last living brother, but he died on the first season.

'(Viserys) always had the big Targaryen (sigil) on his chest and now she's got the big chain with the dragon's heads on it,' Clapton said.

One thing of note was the few times Daenerys wore a silvery grey sash instead of the red.

Daenerys in season seven, episode four, 'Spoils of War.'

The first time this appeared was in 'Spoils of War,' the episode in which Daenerys and Jon Snow share a quiet moment in the dragonglass cave. The colours of House Stark are grey and white, so this might have been a nod towards her growing affection for Jon.

Then Clapton really turned up the dial when Daenerys rocked this striped fur coat on 'Beyond the Wall.'

Clapton created something unique for Daenerys' first trip north.

The majestic nature of this coat was meant to reflect Daenerys' choice to be a hero for Jon Snow.

'She is putting herself and her precious dragons at risk and who for? A threat? A King?' Clapton told INSIDER. 'Dany is elevating her look to that of warrior queen.'

The beautiful fur stripes matched her hair colouring closely, and accentuated her dragon chain.

Unfortunately, one of her dragons died on this day.

Ser Jorah Mormont in another character who got a drastic new costume this season.

Iain Glenn plays Jorah on 'Game of Thrones.'

For six seasons, Jorah wore the same increasingly tattered yellow tunic. But then he was infected with greyscale and had to go to Oldtown for the cure.

When he returned to Daenerys' side, he had new black armour -- complete with striped fur sleeves.

Look closely for the stripes of black fur.

This might be a nod to House Mormont bear sigil. Plus Jorah is frequently described in the book series as very hairy.

Here's a full look at Jorah's new armour and black cloak:

Jorah's new outfit didn't last long, though.

He changed into furs for the risky venture in 'Beyond the Wall,' but we're hoping to see more of Jorah's incredible furry sleeves on season eight.

Speaking of magnificent furs, Jon Snow has never looked more regal.

Jon Snow was crowned King in the North at the end of season six, and so he's spent season seven donning his most kingly apparel.

His billowing fur cape looked fantastic during all of his cliff-brooding scenes.

Jon knows how to walk like a king/

Clapton made waves when she revealed that she used IKEA rugs for the Night's Watch capes, but Jon's 'King in the North' cape is definitely not a wool rug.

When Jon wasn't wearing a cape, you could see his leather armour.

Jon Snow still looks regal, even without all the fur.

Though this leather piece and the undershirt are usually brown and blue, respectively, Jon's leather has become much darker. The blackish quality of the colouring might be a nod to his secret Targaryen parentage.

Jon also changed into his Wildling-esque furs for the voyage beyond the Wall.

This felt like a throwback to his days spent with Ygritte.

The mottled furs and leather helped Jon blend in with the snowy surroundings, but this was a temporary look.

On the season finale, Jon is back in his King in the North regalia.

The fur seems like overkill for sunny King's Landing.

This will be Jon Snow's first time in the capital of Westeros, so it's fitting for him to wear his most regal and intimidating outfit.

Queen Cersei has been all about striking black gowns this season.

Lena Headey as Cersei Lannister.

After crowning herself Queen of the Seven Kingdoms, Cersei has restricted her colour palette to black and silver. The leather dress she wore in the first episode was reminiscent of her father Tywin's early outfits.

Here's Tywin Lannister on the first season of 'Game of Thrones':

Cersei always admired her father's ruthless ethos and strong hand. It makes sense that she'd want to echo his clothing now that she's queen.

Clapton took Cersei's shoulder padding and embroidery to the limits this season.

When we saw Cersei 'welcome' Euron into the capital, her gown was even more extreme.

'It's actually quite ornate and over the top and that's a precursor in a funny way -- it's the last gasp before something else, in my sense,' Clapton told INSIDER. 'It's a weird flamboyance, but it's quite hard as well.'

Here's a closer look at the jeweled lion on Cersei's shoulder:

The jewels and glass are beautifully sewn together.

'At this stage, everything has reached such a zenith in their character development that everything they do and say symbolically means something,' Clapton said. 'From the brittleness of the glass on Cersei and the metal rings on Dany (...) we try to be really symbolic about everything everyone wears now.'

And for his part, Euron seemed to be matching the black theme.

Pilou Asbaek as Euron Greyjoy.

His textured black jacket and tight pants were a new look. Some viewers thought Euron's outfit looked to modern -- like an alt-rock version of Captain Jack Sparrow.

By the finale, Cersei's embroidered shoulders were replaced with a soft fur cape.

Helen Sloan/HBO
The high neckline and black theme persists.

This could symbolise a softening with Cersei, given that she's now pregnant with Jaime's child. Perhaps pending motherhood is helping dial Cersei back?

In her meeting with Daenerys and Jon, Cersei wears yet another style of gown.

Macall B. Polay/HBO
Stripes are clearly trending in Westeros.

This new gown has a softer plain black fabric over the striped long-sleeved gown, the pattern of which almost looks like chainmail. The Lannister lion sigil is placed right below Cersei's throat like a brooch.

Interestingly, Cersei's brother Tyrion is also in on the striped trend.

Macall B. Polay/HBO
Peter Dinklage as Tyrion Lannister.

The early episodes of season seven show Tyrion in a striped doublet with his silver 'Hand of the Queen' pin.

But in the finale, Tyrion's costume looks more similar to Cersei's leather gown in the early episodes. Perhaps their roles are flipping?

Tyrion looks displeased.

In Tyrion's first confrontation with Cersei (after killing Tywin back on the fourth season) it seems fitting that his costume is also reflective of Tywin's early outfits.

Meanwhile Sansa is in the north and has reclaimed her independence.

Sophie Turner stars as Sansa Stark.

Clapton told HBO that Sansa's new leather belt and tight dress is a message to Littlefinger.

'This is her taking back control of her body,' Clapton told HBO. 'I designed it to wrap around over her side-laced dress to represent the absolute removal of any possible physical touch. Her dresses are also tightly laced on, incredibly difficult to remove.'

Sansa is also wearing lush furs, marking her as the Lady of Winterfell and Jon Snow's temporary replacement.

Sansa is ready to rule.

Sansa really came into her own this season, proving she is a capable political force in Westeros. Her new costume reflected both her independence and growth as a woman.

We also want to take a moment to recognise Brienne and Podrick's new fur capes.

Helen Sloan/HBO
Daniel Portman and Gwendoline Christie as Brienne and Podrick.

In our heads we'd like to imagine that Sansa sewed these capes herself, just as she did for Jon Snow on the sixth season. Brienne and Pod are extremely loyal to the Stark family, and serve as Sansa and Arya's protectors.

Speaking of Arya, she also got a new set of threads this season.

Helen Sloan/HBO
Arya in season seven, episode two, 'Stormborn.'

Arya began the season in the Riverlands where she killed the entire male line of Freys, and then was planning to go south. She was wearing a tatted cloak and looked like an experienced traveller.

But when she decided to return north and go to Winterfell, her costume became more reminiscent of her highborn status.

Helen Sloan/HBO
Her new cape and leather top indicates her family's wealth.

Once she was in Winterfell again, Arya switched to rich fabrics in the muted brown and blue colours most Starks wear. Her asymmetrical fur cape was also similar the cape Ned Stark used to wear on season one.

That cape also likely makes it easier for her to access her favourite weapon, Needle, or the catspaw dagger that Bran gave her. Arya is ready to fight at a moment's notice.

Here's a head-on look at Arya's new fashion. She stands apart from Sansa's softer furs and gown.

Arya is a warrior, while Sansa is a lady.

Arya has always embraced a less-feminine way of dressing, and her new costume reflects this personality. The leather and furs still embody her highborn background while maintaining a strength typically reserved for male characters. Arya, as always, is anything but typical.
