The navy blue letter-patterned fabric exudes a retro charm. The letter-textured surface of the fabric presents a delicate layering under the light, with a season-appropriate soft touch and a slight texture. The texture similar to that of a vintage sweater makes autumn and winter outfits more warm and cozy. The classic flat lapel and two-button design retain the dignity of a retro Suit: The Angle of the collar has been treated with a "slightly round" shape, making it look more gentle. The shoulder line adopts the "natural shoulder" process, fitting most shoulder shapes. It is neither overly stiff nor saggy. The small metal logo on the left collar, with a retro bronze texture, forms a warm contrast with the navy blue fabric, adding a touch of modern detail to the retro style. The side-attached bag design makes the bag shape looser than traditional suits, allowing for easy placement of items like folding umbrellas. At the same time, the "slightly sagging" silhouette enhances the casual feel. The fit is slim but not cramped. When paired with a white T-shirt, it can create a "retro Relaxed Style". When paired with a striped shirt, it can recreate the classic outfits from old movies. It is the top choice for men who prefer a low-key yet detailed look. Whether visiting a retro market, watching old movies, or having a date at a coffee shop, wearing it can easily create a retro feel.
