The Android Recovered From the Sea Floor
ATRI is the cheerful, high-performance android at the center of ATRI -My Dear Moments-, a visual novel that was also adapted into a 2024 TV anime. She is recovered from the sea floor, and her signature look is a loose white sailor dress worn with a wide blue collar and a red neckerchief knotted at the front. This costume is built around that exact combination, right down to the collar color and the neckerchief's placement. It's a quiet, everyday design rather than an elaborate one, which is exactly why it reads so clearly as hers.
Inside the ATRI Sailor Dress
The dress is white and long-sleeved, finished with a blue collar and matching blue cuffs. The red neckerchief is a separate piece that ties on over the collar, matching the way ATRI wears it. Both the dress and the neckerchief are made from polyester. A wig, hair ribbons, socks, and shoes are not included, so those pieces are left for you to bring yourself if you want to build out the character beyond the dress itself.
Sizing From S to XXL
This sailor dress is offered in five labeled sizes, S, M, L, XL, and XXL, which covers a wide span of adult frames. Because the dress itself is cut to hang loosely rather than follow the body closely, choosing a size here is less about chasing an exact number and more about picking the label you'd normally reach for in a similar anime costume. If you've ordered sailor-style pieces before, that same size should carry over to this one. Having five sizes to choose from also means there's room to size up or down depending on how loose you want the dress to sit.
Finishing ATRI's Look
The listing covers the dress and neckerchief, so the rest of ATRI's appearance is built from pieces you bring yourself. A long wig in a grey-blonde shade, tied off with red ribbons that pick up the neckerchief's color, gets you close to how she's drawn. Plain white socks are the other piece worth adding, finishing the outfit at the ankle without competing with the collar and neckerchief up top. Together, the wig and ribbons do more to establish the character than any other single addition.
The Gallery and Where to Wear It
These photos cover the dress from the front, from an angle, and from the back, along with a dedicated close-up of the neckerchief. That detail shot is worth studying before you order, since it shows exactly how the neckerchief sits against the collar and how the knot is tied, which is useful if you're planning to match ribbons on a wig to the same shade.
Because ATRI's look is calm and recognizable rather than elaborate, this dress works well for Halloween gatherings, convention meetups, or any adult costume event where you'd rather be instantly recognizable than buried in accessories. The collar and neckerchief alone carry the character, so pairing it with the right wig is really the only extra step. The dress is listed in the site's anime costume and Halloween costume categories, alongside other adult-sized cosplay outfits.
