Product Insights
Poplin Shirtdress 65% polyester, 35% cotton. Deliberately loose, wide and androgynous with broad sleeves. Take your usual Sacai size for the intended volume; size down only for a closer fit. Dry-clean only: do not wash, bleach or tumble dry; iron with or without steam. Voluminous cut, polyester-dominant poplin and dry-clean care are the main compromises.

Slipping a hand into the side seam opening
In the product image, the shirtdress's wide three-quarter sleeve features a side seam opening that works as a pocket — a model's hand is shown inserted there, creating a visible triangular opening at the side. That gives a casual place to rest a hand while wearing the dress.[2]
Product comparison
Compared within this brand.
| Poplin Shirtdress: Choose this if you want a loose, above-the-knee shirtdress with androgynous volume — the merchant describes its wide fit, broad sleeves and minimalist-yet-contemporary design as defining Sacai's eccentric expression. It is made of lightweight 65% polyester and 35% cotton poplin in black, with a hidden front placket, chest and side-seam pockets, a back box pleat, and buttons on the wide buttoned cuffs, and is made in Japan in sizes 1, 2 and 3. Note it is polyester-heavy rather than pure cotton, and the image analysis reports both a rounded hem and a straight, even hem, so the hemline detail is not fully consistent.[1,3,4] | Layered Effect Tie-Neck Shirt Dress: Choose this if you want a loose, straight-fit short shirt dress with a distinctive layered high-low hem and Sacai's bold, quirky aesthetic in preppy light blue pinstripes. It features a tie-neck collar with a long dark navy ribbon, button-front placket with buttoned cuffs, a patch chest pocket, and a cotton-polyester poplin (75% cotton, 25% polyester) made in Japan. Note the listed variant shown is size 1 in Patterned Blue, and the layered front panel covers most of the placket.[5,6,7,8] | Nylon Sleeves T-Shirt Dress: Choose this if you want a Sacai piece described by the retailer as a fusion of utilitarian precision and feminine design, with practical pocketed sleeves and sculptural volume reworking a classic T-shirt silhouette. It pairs a matte cotton jersey body and ribbed crewneck with short, slightly puffed shiny nylon raglan sleeves that feature a zippered sleeve pocket, and it comes in black in a straight, cropped cut ending above the knees. Made in Japan, it is lined in cupro, so it suits shoppers drawn to statement construction over a relaxed everyday shape.[9,10,11,12] |
