Sanrio, the Japanese brand best known for the creation of the famous Hello Kitty, has been an international sensation since the mid-1980s. In recent decades, Sanriocore has emerged and gained popularity among enthusiasts. The Sanriocore aesthetic, sometimes known as Hello Kitty Y2K, is best characterized by its cute, playful, and often edgy styles, incorporating various Sanrio characters onto clothing and accessories. This guide will explore the origins of Sanriocore, its key pieces, and what defines the perfect Sanriocore/ Hello Kitty Y2K look.
What is Sanriocore?
Sanriocore is an aesthetic that is centered around the cute Sanrio characters, stories, and more. This term refers to any one of the Sanrio Brand characters or a combination of multiple characters’ styles. Sanriocore may immediately be known in a fashion sense, but it extends to home decor, stationery, vehicles, and anything that a character can be printed on.
The fashion of Sanriocore is eclectic, blending cute and playful, and sometimes with a little dark edge. The colors and silhouettes are bright and cartoon-like, paying homage to the cheeky world the characters hail from.
The History of the Sanriocore Aesthetic
Sanriocore is centered around the early 2000s, so many of the Sanriocore garments are inspired by many of the styles and silhouettes of the Y2K fashion era. The first ever Hello Kitty accessory was produced in 1974, a coin purse sporting Hello Kitty with a glass of milk and her goldfish. She grew to become a pop culture phenomenon in the mid-80s both in Japan and on the international stage. She perfectly encapsulated “kawaii”, the Japanese word for “cute” – the “kawaii” culture emerged in this era, and Hello Kitty was a major contributor to this movement. In the decades since, more characters were born and more merchandise like clothes, video games, shows, and even theme parks were created. The fashion-side of the market came to prominence in the early 2000s and Sanriocore was a thriving, international aesthetic.

Today, new pieces are produced to be reminiscent of this era in fashion, and vintage pieces are highly sought after.
Sanriocore Key Pieces / Clothing and Accessories
Sanriocore fashion draws inspiration from various subcultures like Pastel Goth, Yanderecore, Softie, and Larme Kei to create a unique blend of cute, quirky, and edgy. Clothes and accessories in this aesthetic combine girly and playful with elements of darkness. Animal ear headbands, bow clips, and face stickers are commonly worn along with heavy blush and bandaids as accessories. Sanrio print tops and character-themed lolita dresses are popular choices. A common pairing is pastel sailor uniforms and knee-high socks. Footwear is bold and cartoon-like with platform shoes such as Mary-Jane or creepers. Plush accessories are a favorite, they include slippers, mini backpacks, plush jewelry, keychains, and phone accessories to complete the look.
Sanriocore features cute make-up that is neutral, but a heavy blush is applied to the cheeks and nose-bridge. The nose-bridge is critical to the look, as it adds an innocent and cartoon-like character. Other additions of glitter, gems, and stickers play into this fun look. One element of the make-up that is very Y2K is lipgloss, as a heavy lip can weigh down the fun of the style. Nail art is a huge component of the style, it often includes the Sanrio characters complemented with pinks and other girly decals.
