Once Upon a Butterfly Twirl Dress & Removable Wings Set

One magical Halloween costume. A favorite cotton twirl dress long after.

Let her imagination take flight in our limited-edition Once Upon a Butterfly Twirl Dress—an enchanting lavender dress designed for Halloween adventures, everyday twirling, and all the make-believe moments in between.

Made from our soft, comfortable cotton-spandex blend, the lavender twirl dress has the stretch she needs for hours of play and a full skirt made for magical spins. Gently pleated sleeves create a sweet puffed shape, giving this versatile dress an elevated, storybook finish that feels special without sacrificing comfort.

The showstopping removable butterfly wings feature an exclusive Only Little Once print in a dreamy palette of soft pastels. Custom-designed to create a timeless butterfly look, the wings attach at the shoulders with buttons and can be removed whenever her magical costume becomes her favorite everyday dress.

She can wear the complete set for trick-or-treating, Halloween parties, dress-up days, imaginative play, and storybook photos—then remove the wings and continue wearing the lavender cotton dress to school, playdates, birthday parties, and everyday adventures.

Because the most wonderful costumes shouldn’t be worn only once.
