"My (very tall!) 20 month old is 36" tall so I ordered the Toddler 3/4 size and it's a perfect fit. She loves Abby so this was the perfect Halloween costume for her. As soon as it was removed from the packaging, she grabbed it and repeatedly screamed "Abby!!" in excitement. So much so, she wouldn't allow me to actually put it on her since she was holding and admiring it. The wings stayed on just fine for our 45 minute trial run and the pom poms are adorable. Also purchased the wand which is sturdy and looks better than I expected (pics made me uncertain of quality). Overall, this will be a hit for mini Abby fans. Enjoy!"
