This is the "Waiter" Ouji Lolita set (by Three Cats Original Design)—a butler-themed ensemble in the Ouji (Prince) Lolita category, drawing inspiration from classic waiter/butler attire (tailcoat-style vest, ruffled shirt, structured shorts). It embodies the "noble servant" aesthetic, blending formal tailoring with Lolita details (oversized ruffles, adjustable waist). Commonly worn at Lolita tea parties, butler-themed events, or cosplay gatherings, it balances elegance and playful formality.

The set includes a tailcoat vest, ruffled shirt, and shorts, crafted from a blend of human cotton and polyester for structure and comfort. Key details: the vest features an adjustable waist (with eyelets for expansion), the shirt has dramatic ruffled cuffs, and the shorts include harness-style accents—all in a black-and-white palette that reinforces the butler theme. The ensemble can be worn as a full set or mixed with other formal Ouji accessories (e.g., bow ties, gloves).
