Is it cultural appropriation to dress up as Lilo?
Would it be offensive to dress as Lilo from Lilo & Stitch? No. Even if you wore her Hawaiian dance costume, it's not appropriation. You're dressing as a character.
It shouldn't matter whether or not a child's ethnicity perfectly matches the character being portrayed as long as their costume is of an individual. It's completely acceptable for a child to dress as a character, not a culture. If my insanely white child wants to dress up as Moana, that should be fine.
Lilo wears a bright red dress with large white leaves printed on it. You can find many styles that resemble her exact dress. You'll also need some black sandals since she lives on the beaches of Hawaii.
Many cosplayers grew up with Dora and have fond memories of her, so putting together your own Dora costume can be a great way to get out and have fun. Start with a pink t-shirt and orange shorts and add yellow socks with white sneakers. Don't forget a purple backpack, just like Dora wears on the show!
I'm happy to let you know that yes, as long as you follow all of the guidelines for attire, you'll be able to wear a dress inspired by Lilo's dress. Have you heard of Disney Bounding?
For example, the 'Japanese rock', a dressing gown, which was worn by wealthy men in the seventeenth century and was seen as a status symbol. But also the Kashmir scarf and the turban. It also happened that clothing that was worn by a man in India or China, for example, was put on by a woman in Europe.
This is what I am reminded of every time I hear someone ask if it's OK for a child who's not Black to go as Black Panther for Halloween. The answer is yes, but there's an important caveat: there can be absolutely no Blackface.
DisneyBounding is dressing like a Disney character using regular clothes. It's a fun way to embody a favorite character without wearing a full costume. You can DisneyBound in everyday life, but it also adds a little extra fun when visiting any of the Disney theme parks.
If your child does decide to dress as a person of another color, it's worth remembering the obvious stereotypes to avoid. Dressing as Moana isn't racially insensitive—thinking you need to smear yourself in brown makeup or don a tinted skin “suit” in order to authentically represent her, is.
The newly released Lilo & Stitch 2, plays equally fast and loose with one of the cornerstones of Hawaiian belief, literature, and dance—with the legend of Pele, Hi'iaka, and Lohi'au.
Is it offensive to dress as a hula dancer?
“Dressing up as a hula dancer, hula being a significant part of the Hawaiian culture, without any consideration or respect for its origins also makes it a form of cultural appropriation— which only makes it more offensive.” The practice of hula itself has also been historically oppressed.

wearing a significant cultural attire to cosplay a character is ABSOLUTELY cultural appropriation. You are wearing cultural attire as a COSTUME. This article will help you understand what Cultural Appropriation is: What Is Cultural Appropriation?
