River Tam Costume Ideas

Brown Wig:

To get River’s hairstyle right, buy a long brown wig and dampen it a bit with gel to best match her style.


River is a fugitive which means she doesn’t have much time for makeup. If you have to, you can use a little concealer to darken the circles under your eyes slightly to get a fatigued appearance.

Flowery and Free-flowing Dresses:

Having being held in a facility for almost two years, River was mostly dressed in clothes that restricted her movement. This is why her fashion sense is a bit on the old fashioned side, but with a free spirit vibe. She is a fan of long, flow dresses and mosaic print.

You can get knee-length dresses in faded blue, green or red as depicted in some of the promo posters. Avoid jeans and accessories such as earrings and bangles. Aim for a more conservative and liberated look.

You may also want to get brown a t-shirt and cut it out to look like the t-shirt she sometimes wears on top of her dresses.

Black Combat Boots:

Being a fighter, River wears calf high boots. Just get a pair of black boots that reach past your calves.


You can equip yourself with a axe or sword prop, specifically a toy katana. These weapons are optional because they mostly refer to the movie ‘Serenity’. Either way, feel free to match them up with the costume described above.
