Galaxy Print is a fashion trend that was highly popular in the early to mid-2010s, characterized by the use of prints that mimic the appearance of outer space. The design typically features imagery of stars, nebulas, and swirling cosmic patterns in vibrant shades of deep purple, blue, and pink. This aesthetic was popularized in the 2014 Tumblr era and was widely adopted in mainstream fashion, appearing on a variety of clothing items from leggings and dresses to sneakers and accessories.

The galaxy print trend emerged around 2011 and reached its peak popularity between 2012 and 2014, a period heavily influenced by online platforms like Tumblr. The aesthetic was fueled by the rise of digital printing technology, which allowed for highly detailed, high-resolution astronomical images to be transferred onto fabric. It became closely associated with the online "Tumblr Girl" persona and the broader Indie Sleaze subculture, which romanticized a quirky, often slightly messy and party-centric lifestyle.

The trend was ubiquitous, found on everything from fast-fashion leggings and skater skirts to high-end designer collections. Christopher Kane's SS10 collection is often cited as an early high-fashion example that popularized interstellar imagery. By the mid-to-late 2010s, the trend's popularity began to wane as fashion cycles shifted. However, designers have occasionally revisited the print, with Kim Jones notably reincorporating it into a Dior menswear collection in late 2022, signaling a potential nostalgic revival.

Galaxy print was most famously applied to leggings, which were often paired with oversized sweaters or graphic tees. Other popular items included skater skirts, mass-produced hoodies (often featuring images of wolves), sweatshirts, dresses, and footwear, particularly Vans and the chunky Jeffrey Campbell "Lita" boots.

The aesthetic often existed alongside other defining motifs of the 2010s Tumblr era. It was frequently paired with accessories like mustache necklaces and clothing featuring other trendy patterns like "Aztec" print. The overall look was eclectic and expressive, often incorporating elements of fantasy with unicorns and aliens, as well as a bright, sometimes neon, color palette. The style was a form of accessible self-expression for young people, allowing them to showcase their interests in science, space, or simply a bold and unique visual style.
