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.
