Frequently Asked Questions (FAQs)

1. How do you dress up a nun costume?

Wear a dress or a long black skirt and a loose, long black shirt or top as a base for a last-minute nun outfit. Alternatively use a large black sheet or piece of fabric. Fold it in half and cut a hole in the center of the fold with scissors, ensuring the hole is large enough fit over your head comfortably.

2. What are nun outfits called?

You know a nun when you see one. The uniform, known as a habit, is a dead giveaway. But the outfit you're picturing in your head might look very different from the one worn by the sisters at your local convent.

3. Is it okay to dress up as a nun for Halloween?

There's always that one goofball friend at the Halloween party who is convinced that dressing up as a sexy nun is oh-so-hilarious. No, buddy. It's not. For many religious people cassocks, veils and turbans aren't costumes, at all, but important elements of their faith practice.

4. What does a nun outfit look like?

In Christian monastic orders of the Catholic, Lutheran and Anglican Churches, the habit often consists of a tunic covered by a scapular and cowl, with a hood for monks or friars and a veil for nuns; in apostolic orders it may be a distinctive form of cassock for men, or a distinctive habit and veil for women.
