Beginner friendly: Easy to start

Rental costumes can be a relatively easy side hustle for beginners, with setup costs ranging from $200 to $500. It's a business that most people can start and earn from quickly, especially if they tap into online platforms like Etsy, eBay, or local social media groups to advertise their costumes. With a bit of creativity and research on popular trends, beginners can attract customers and make a profit within 2 weeks. I'd rate it a 4 because the demand for costumes is consistent, startup costs are manageable, and online selling channels make it accessible for newcomers.
