50+ Tween Girl Halloween Costume Ideas

Halloween costumes used to be easy for my baby girl, but as she’s entered her tween years, we’ve consistently had a more difficult time finding age-appropriate costumes that she both likes and are in her size. Perhaps the skirt is too short, the top cut too low, or the name of the costume always has the adjective “sexy” in the title – seriously, a sexy crayon costume? – so, like me, you’re looking for tween girl Halloween costume ideas! After much searching (and searching, because it took A LOT of digging), here is a nice list of 50+ Halloween costume ideas for your tween girl that you can feel good about as she goes trick-or-treating! Some are DIY, others are linked with affiliate links (thanks for your support!), but all are costumes I would feel comfortable with my 10-year-old wearing. Have a fun Halloween everyone!
