Some examples of gifts that a 13 year old would like include jewelry such as bracelets, cell phone accessories, gift cards and cosmetics. You can also get her concert tickets for one of her favorite bands.
Im 13 and i guess it depends on what she likes. Find out her shoes style and get her new shoes( never clothes we can get that ourselves shoes cost more. Jewelry and elecronics work. If your on a budget mabey a case or gift card to her favorite store:)
