Are bandannas allowed? Photo added for reference of size

I love to knit and I’d love to make myself a cute bandanna/small head kerchief that I can wear at work. I recently had a bald spot appear on the top of my head and it’s very noticeable and I’d like to cover it up without having to wear a tight headband that might make my problem worse. Would a bandanna be acceptable to wear? If it’s helpful for reference I am a female.
