At the heart of Paris Fashion Week, a key question has been on everyone's mind: what makeup trend is set to define the spring-summer 2027 season. The answer lies in a dramatic shift in lip makeup, moving away from sharply defined outlines toward a trend known as the "bit唇" effect. This term, which translates to "bit lip" in English, describes a look where the lip color slightly overflows the natural lip line, creating a soft, diffused appearance. The trend emphasizes bold red shades, including orange and raspberry tones, replacing the traditional burgundy lipsticks that have been popular in recent years. On the runways of major fashion houses like Lanvin, Tom Ford, Dries Van Noten, Julie Kegels, and Victoria Beckham, orange-red lip colors have taken center stage. These shades are paired with a fresh, minimalist complexion, often devoid of heavy eye makeup such as mascara or eyeshadow. This aesthetic choice highlights the lips as the focal point of the face while subtly drawing attention away from minor imperfections. The effect is both striking and elegant, emphasizing a natural yet bold beauty. The raspberry red lipstick, in particular, has been a standout, especially when paired with paler skin tones. This was prominently featured in the Valentino show, where the color complemented the models' complexions beautifully. The "bit唇" effect is achieved by applying the lipstick gently and blending it outward with a finger, ensuring a seamless transition between the lip color and the skin. This technique helps create the soft, diffused look that defines the trend. As the spring-summer 2027 season approaches, the "bit唇" effect is expected to influence not just high fashion but also everyday makeup trends. Makeup artists and beauty brands are already preparing products that cater to this new aesthetic, signaling a shift in how people approach lip makeup. This trend reflects a broader movement in fashion toward minimalism and natural beauty, while still embracing bold and expressive elements.
