My daughter is 4 years old, will be 5 next month and she was a bit big. I had to tie the straps in a knot at the back to make them fit, but they stayed on her for the full four hours if she wore them as a breast or as a treat. This is a genuine Disney wig and is exactly as pictured. It had a very slight chemical smell probably due to the plastic bag it was in so I let it air out for a day and it was gone. It's cute, very soft, we don't recommend tangles.
