These are Disney bounding dolls and made for park fans about park fan culture. The mickey balloons and minney ears are big give away that that's what they are going for. I wouldn't be too surprised if you could buy some of these doll clothes in people size from there and these dolls are working as marketing too. You can wear same shirt as your doll because it's literally you, Disney magic and pixie dust.
Basically in the Disney parks anyone over 10 aren't allowed to dress as Disney characters outside of Halloween parties. Main reasons given are child safety and keeping the magic. Disney spent quite alot time training and organizing the actors so they look and act right and that you can't see duplicates of characters at once. Naturally random members of the public won't know, let alone have any real reason to follow the scrip so ban on cosplay. Also meet and greets are big business for them and don't want the competition.
Still some adults want to dress up for the parks to feel like they are part of the disney magic. What they do instead is Disney bounding or dressing up so they follow the spirit, form and/or colors of a character, movie or attraction but aren't directly costumes from these things. Recognizable but different enough not be confused to working there sort of deal.

That's why obliviously wrong race on the dolls so that you aren't confused if these are the princesses in modern clothes, they are not. Okey, they are confusing to people not into the park culture but to that target audience it's perfectly clear what these are. Honestly I think the packaging is to blame on that front alot. If they hadn't put the princess in front and had instead done something like the doll girl hugging a movie plushie it would have been much more clear. These dolls are just themed around the princesses and loving them but not depicting the princesses directly.
