Product Insights
Sacai's button-up mock-neck wool cardigan uses side snap vents to toggle between a straight, body-following silhouette and a flared shape that reveals layers, embodying the brand's hybrid design ethos from its knitwear origins. The fine 100% wool knit provides three-season thermal regulation while demanding dry cleaning, and the mock neck lies flat for clean layering under collars or standalone wear. Priced at $895 CAD, it avoids the premium of Sacai's scarf-collar cardigan, offering added design details and multiple styling options as a top or under a blazer, though its complex construction and professional care requirements are tradeoffs.

Speculation on Sacai sweater construction
I rewatched the video. I’m now thinking the white band at the bottom is stiff fabric because the sweater flares out all the way around. Sacai uses a mix of sweater knit and fabric in their collections.
