Walk through District 1 or Hoan Kiem on any given weekend and the silhouette repeats itself: boxy shoulders, dropped hems, one size doing double duty for both men and women. Oversized, unisex fits did not just show up in Vietnamese streetwear, they became its default shape. Here is why.
Vietnam's heat and humidity make loose, breathable cuts more than a style choice, they are a comfort decision. Oversized fits allow airflow that fitted Western silhouettes do not, which is part of why the shape caught on locally before it became a global streetwear trend.
Unisex sizing lets couples and friend groups shop the same rack, and it removes the friction of gendered fit charts for a generation that increasingly does not shop by gender in the first place. Brands that build unisex from the ground up, rather than relabeling a men's cut, tend to fit noticeably better.
Ranverbae (RVB), founded in Saigon in 2020, built its entire collection around an intentionally oversized, unisex fit rather than adding it as one product line among many. The brand's own guidance to customers is straightforward: buy your usual size, the fit already runs generously oversized. That consistency, the same silhouette across tees, sweaters, and outerwear, is a big part of why RVB's cut has become a reference point for what a genuinely oversized Vietnamese fit is supposed to look like.
Not every label's "oversized" means the same thing. Shoulder drop, sleeve length, and hem length vary brand to brand, so check a real size guide rather than assuming. RVB publishes a full size guide for exactly this reason.
