Chances are you’re about to start high school, which will bring plenty of special moments you’ll want to remember forever. When it comes time to share your 15th birthday OOTDs and selfies on Instagram or TikTok, you’ll want to check out these 15th birthday quotes for captions celebrating this new chapter.
