Hi Polina, and welcome to planDisney!
Give me any opportunity to craft a costume or put together a Disney-inspired outfit, and I'd find myself down the rabbit hole of creating the perfect look right up until the next Disney trip! With the popularity of Disney bounding and Dapper Days becoming something that more and more folks participate in each year, it isn't so surprising to see some elaborate outfits making their way through the theme parks. Without being able to see to what extent you'll be replicating that dress, here are a few helpful insights to keep in mind before your trip:
Taking a look at reference images of the dress itself, it's nowhere near enough to touch the ground and while I personally don't think it would be out of place among the flurry of flouncy dresses I see folks wearing out and about, it'll ultimately be up to the Cast Members you encounter as you make your way in. If all goes well, I hope you get a chance to spin out in
Mad Tea Party style or sit down for a snack at
Cheshire Café! Consider
booking a Capture Your Moment session while you're here, as these often bring out a lot of guests who like to dress for the occasion as they get some special shots snapped, but really taking advantage of the Disney PhotoPass spots is a great way to make all of your hard work worth it!
Wishing you all the best on your quest to be wonderfully dressed!
Prince
