To restore Jade's elegant and slightly mysterious Onee-san temperament, I made many detailed considerations in this cosplay. First is that huge black wide-brimmed hat, which is the visual center of gravity for the entire look, instantly creating a premium sense of oppression. Paired with the long hairstyle I designed, it makes the character's silhouette more three-dimensional. Regarding the costume, I paid great attention to the premium feel of the black and white color-clashing, trying my best to match the original noble texture of the character in the choice of materials. Especially the decorative details on the cuffs and the design of the waist are all meant to balance the visual center of gravity. For the makeup and styling, I chose slightly cool tones to set off the character's cold temperament while retaining enough mature beauty. To match the entire scene, I specially chose a vintage red velvet chair and made multiple adjustments to the lighting layout, utilizing warm-toned light and shadow to complement the golden decorations in the environment, creating a unique Atmosphere of loneliness amidst prosperity. Throughout the creative process, I always insisted on doing thorough homework on clothing craftsmanship and detail restoration, striving for every lens to precisely capture Jade's core charm as an Onee-san / Mature woman, hoping to give everyone the most perfect visual experience.
