Wig size question

I have Ladybug-- and on BB it says she takes a 16-17 size wig. However when I measured her head myself, it was 15"
… am fairly sure I measured correctly.
Do i still keep on looking for the 16 size wig?

thank you for putting up with all my questions.

I haven’t tried using wigs but I’m sure if you call BB’s customer service, they can help you or will find out for you. They have been great about that type of problem when I had questions about products. This is one company that seems to really take pride in customer service.
