Grandpa Core: The cozy, quirky aesthetic that took fashion by storm

Key takeaways

  • Grandpa Core blends vintage comfort and quirky style, redefining fashion with nostalgic, gender-fluid pieces.
  • The trend reflects a cultural shift toward emotional storytelling, sustainability, and slow, mindful consumption.
  • Popular among Gen Z and Millennials, Grandpa Core offers brands a unique opportunity to connect through authenticity and heritage.

In a fashion world that constantly races forward, the most powerful trends often come from slowing down. Grandpa Core, a charmingly nostalgic aesthetic rooted in comfort, utility, and vintage charm, is doing exactly that. Born from the depths of thrift stores and family wardrobes, this emerging theme is quietly redefining how consumers relate to clothing, value memory, and express personality.

Heuritech’s expert fashion team identified Eclectic Grandpa as a fast-rising aesthetic at the start of the year. With its blend of vintage sensibility and gender-fluid appeal, it offers fertile ground for designers and brands looking to tap into emotional storytelling and real-world resonance.

What is Grandpa Core?

Grandpa Core is an aesthetic inspired by the classic, utilitarian wardrobe of elderly men, reinterpreted through a contemporary lens. The look features elements like oversized knit cardigans, wool pants, orthopedic sneakers, and retro accessories, all styled with intention and playfulness.

It’s not about dressing “like a grandpa” in a literal sense, it’s about embracing clothing that feels familiar, humble, and oddly fashionable. Think Tyler, The Creator in slouchy slacks and loafers, or Emma Chamberlain pairing vintage trousers with knit vests. It’s style as storytelling: nostalgic, accessible, and personality-driven.

Why now? The cultural drivers behind Grandpa Core

Nostalgia as comfort

In an age of digital overload and societal uncertainty, consumers are seeking comfort in the past. Grandpa Core taps into this emotional need with pieces that feel inherited, lived-in, and grounding. 

Normcore evolves

The past seasons have been dominated by the core aesthetics. Where Normcore embraced anonymity, Grandpa Core infuses warmth and character. It’s Normcore’s softer, quirkier sibling, favoring mismatched prints, textured knits, and an appreciation for the mundane. The result is a more emotionally expressive and style-forward version of utilitarian dressing.

The rejection of hyper-stylization

After years of polished, curated aesthetics, Grandpa Core signals a return to unfiltered, comfortable dressing. It prioritizes substance over spectacle, clothes that feel good, not just look good. It’s a quiet revolt against fast fashion and performative trend-chasing.

Gender fluidity and soft masculinity

Grandpa Core is inherently inclusive. While its origins lie in traditional menswear, the aesthetic has been widely adopted by women and nonbinary creators. The oversized silhouettes, muted palettes, and functional footwear align with the growing movement toward gender-neutral fashion and soft masculinity. 

Key product elements of the Grandpa Core theme

These items define the Grandpa Core wardrobe. Each piece offers styling versatility, emotional appeal, and retail adaptability.

Clothing

  • Chunky cardigans and coats. In earth tones, vintage patterns, or fair isle knits. Look for oversized fits, shawl collars, and tactile yarns.
  • Pleated or wool trousers. High-waisted and relaxed, often cuffed or slightly cropped. Corduroy and tweed variations add texture.
  • Knitted vests. Worn solo in warmer weather or layered over a shirt. A unisex staple with high layering potential.
  • Oversized blazers and polos. Patterns like houndstooth or horizontal lines evoke academia and vintage tailoring.

Footwear

  • Orthopedic sneakers. Retro silhouettes like New Balance 990s and Asics are key. Function over flash.
  • Loafers, moccasins, derby shoes. Slightly clunky soles bring a retro charm. Often styled with socks prominently visible.

Accessories

  • Wire-frame or tortoise-shell glasses. A wink to academia and introspection—popular among Gen Z for their bookish appeal.
  • Socks and sandals. A playful styling choice that blends comfort with norm-defiance.

Cultural and market context

A cross-generational revival

Grandpa Core has transcended niche fashion circles and entered mainstream conversation. TikTok creators style thrifted pieces with reverence; celebrities like Harry Styles and A$AP Rocky embrace its layered silhouettes on red carpets. Brands such as Bode, Aimé Leon Dore, Séfr, and Our Legacy have woven its sensibility into their core identity, reviving vintage craftsmanship with a modern twist.

The analog and sustainability effects 

The aesthetic aligns with broader cultural shifts toward analog hobbies: film photography, vinyl, knitting, gardening. These slow, tactile practices echo the emotional texture of Grandpa Core, an aesthetic rooted in care, history, and domesticity.

Grandpa Core also complements sustainability narratives. Its foundation in secondhand, vintage, and heirloom pieces encourages reuse and mindful consumption. This makes it a natural fit for eco-conscious branding and storytelling, two critical pillars in Gen Z purchase behavior.
