款式 refers to the style, design, or aesthetic form of a physical object—especially clothing, accessories, furniture, or consumer products. The character 款 (kuǎn) originally meant 'item' or 'category', and 式 (shì) means 'form', 'pattern', or 'style'; together, they emphasize the outward, visually distinctive characteristics that define how something looks and fits within a trend or function. It’s commonly used when comparing or selecting items based on appearance rather than material or price.

This word appears frequently in shopping contexts, fashion discussions, product descriptions, and interior design. Unlike terms like 风格 (fēnggé, 'personal style' or 'artistic genre'), 款式 is more concrete and object-focused—it describes the tangible shape, cut, silhouette, or decorative details of a thing. It’s neutral in register and widely used in both spoken and written Chinese, especially in commercial and everyday settings.
