The suit is centered on a classic lapel girls denim vest, paired with a simple solid-color suspender jumpsuit, creating a new Korean children’s clothing style. The vest is designed with a single-breasted button, and the stiff denim fabric is combined with a retro lapel to add a casual street feel; the jumpsuit uses a loose wide-leg pants style and suspender cut to balance vitality, and the solid-color base highlights the refreshing temperament. The combination of the two can not only highlight the sense of layering, but also change the style by disassembling and matching, meeting the needs of multiple scenarios such as daily street outings and vacations. The suspender jumpsuit worn inside the vest is made of 65% cotton + 35% polyester fiber fabric, which is light, breathable and has good ductility, making it convenient for children to run and jump. The high-waist design of the jumpsuit modifies the proportions, the shoulder straps are adjustable to prevent slipping, and the back buttons are easy to put on and take off; the denim vest uses a washed process to soften the material, and the lapel edge stitching is neat and wear-resistant, taking into account wear resistance and skin-friendly feeling, especially suitable for flexible switching between summer sun protection and air-conditioned room warmth.
