Based on current public chatter, there isn’t a confirmed official Daisy Duck costume for MNSSHP 2026 yet. The most plausible guess is a Halloween-themed or witch-inspired look, with fan discussion often pointing to purple and star accents, but that remains speculation rather than an announcement.

What’s known

Mickey’s Not-So-Scary Halloween Party is scheduled for 2026, but the detailed character costume lineup has not been officially published in the sources I found. One recent Disney-related appearance shows Daisy in a purple dress and hat for a spring display, which is unrelated to Halloween but does reinforce that Disney often gives her highly themed seasonal outfits.

Best guess

For a party like MNSSHP, Daisy is most likely to appear in one of these styles:

  • A witch costume.
  • A spooky-cute Halloween dress with purple details.
  • A coordinated “friends” seasonal outfit alongside Mickey, Minnie, Donald, and Goofy.

Why people think that

Fan posts and costume-idea pages often lean toward purple, stars, and a bow- heavy design when imagining Daisy for Halloween events. That fits Daisy’s usual style: elegant, playful, and a little extra.

TL;DR

No official 2026 Daisy Duck costume has been confirmed yet. The safest current answer is that she’ll probably wear a Halloween-themed look, and the fan favorite is a witchy purple outfit.
