Ada from Lamb
Ada is a character from the A24 film called Lamb. Lamb is a fantasy/horror film that takes place in rural Iceland. A couple there discovers an unnatural newborn lamb in their sheep barn that is a human and sheep hybrid, and decide to take in the lamb as their own.
This character would make for a hilarious and clever costume for movie fans, especially those who enjoy horror and A24. For the past few years we have seen A24 themed costume parties pop up in viral videos around Halloween every year, especially when people get super creative, so this would be a great one for that. To dress like Ada, wear a lamb/sheep mask or hat with ears, a wildflower crown, a navy raincoat and blue cable-knit sweater to create this recognizable look from the film.
