Greetings, Kimberley!
Welcome to the Disney Parks Moms Panel. I love that your daughters are so enthusiastic about dressing up for their vacations to the Disneyland Resort. I also love planning my outfits each visit. It's part of the whole Disney vacation experience!
I have looked many times throughout the Resort and have found Princess dresses to only go up to a size 9/10. This is similar to the selection you will find at your local Disney Store or
shopDisney.com. I have seen many young Guests dress in homemade or third party costumes if certain styles and sizes are not available through Disney. Your daughter may fit the women's sizes better if she has outgrown the children's dresses. While Princess dresses are not currently being sold in adult sizes, there are actually a number of other really cute dresses and Princess-inspired clothes available.
Another suggestion is to look into the trend of "
Disneybounding." This is a fun take on dressing like your favorite Character without wearing an official costume. Many Guests take part in this fun fashion trend by wearing the iconic colors and styles of Characters. You will see many children and adults Disneybounding in the parks. It's always fun when you spot someone doing this as it isn't always obvious at first, so it kinda feels like a game when you spot one. I always make sure to compliment a fellow Disneybounder on their unique look.
Since you are a
Canadian resident, I also just wanted to inform you on a great ticket offer available to you. This will give you savings on 3-Day to 5-Day tickets at the Disneyland Resort.
I hope this helps, and have a magical day!
