Rhaenys Targaryen Halloween Costume Guide

The council passed her over for the throne for one reason: she was born a woman. She never says a word about it in public.

Rhaenys Targaryen had a better claim to the Iron Throne than her cousin Viserys, and the Great Council chose him anyway, for no reason beyond his sex. She never fights that decision in public, which is its own kind of statement. The silver wig and the ruby jewelry set are what make this costume specifically Rhaenys rather than any other Targaryen woman. Eve Best plays her in House of the Dragon (Wikipedia), and while the show is a genuine HBO hit, Rhaenys herself is a supporting player next to Rhaenyra and Alicent, the two women the plot actually centers on.

How to Style the Rhaenys Targaryen Halloween Costume

The silver wig is what people clock first, since it’s the fastest signal of “Targaryen” in the whole show’s visual language. Without the ruby jewelry breaking up the silver-and-gown palette, the costume can flatten into generic fantasy royalty rather than anything specific to Rhaenys. At a party, a cheap costume-shop gown under good jewelry still reads better than an expensive gown with nothing on the neck and wrists.

Rhaenys sits through the Great Council in 101 AC and watches the realm hand the throne to her cousin instead of her, purely because he’s a man. She doesn’t argue, doesn’t storm out, doesn’t even raise her voice about it on screen. She just remembers it, for decades, which the show keeps circling back to.

Braid at least part of the wig

A fully loose wig reads as generic fantasy hair. Even a single small braid pulled back from the temple signals the specific styling the show uses and takes under ten minutes to do.

Don’t overdo the makeup

The character’s actual look leans natural rather than heavily done. Bold contouring or dramatic eye makeup will fight with the wig and jewelry instead of supporting them.

Rhaenys Targaryen Halloween Costume DIY Tips

Building the Look

The gown and wig are worth buying with intention, the jewelry is where you can economize.

  • Gown: buy this one, or thrift a flowing dress in red, gold, or black if you’d rather source it yourself.
  • Wig: buy this, a genuinely long, curled silver wig isn’t something most people own.
  • Jewelry: check your own collection first for anything red-stoned or gold-toned before buying new pieces.

Playing Rhaenys Targaryen at the Party

Rhaenys is composed, sharp, and rarely raises her voice. Play the restraint, not a dramatic queen performance.

  • Speak less than you normally would. Let a raised eyebrow do the work of a full sentence.
  • If someone makes a bad decision near you, don’t stop them, just note it quietly for later. That’s very on-character.
  • Stand still and let people come to you rather than working the room yourself.
  • Skip the melodrama. Her strength in the show comes from restraint, not outbursts.
