Gen Z Ditches Blue Denim Jackets as 'Mumcore', Embracing 'Office Siren' and 'Coastal Grandma' Looks

The blue levis jacket, once a staple for millennials, is now facing a shift in perception. Gen Z sees it as a sign of age, even dubbing it 'mumcore'. Meanwhile, new trends like the 'Office Siren' and 'Coastal Grandma' looks are emerging, and fashion lovers are moving towards different styles of outerwear.

For years, the blue levis jacket was the uniform for millennials, praised for its versatility. However, Gen Z now associates it with age, with a TikToker, Joce, suggesting that spotting someone in a blue levis jacket places them at least 31 years old. This generation considers it a 'mumcore' item, alongside other millennial relics like infinity scarves and jeans.

The fashion landscape is evolving. The 'Office Siren' and 'Coastal Grandma' looks are trending, replacing 'Corporate cool'. These styles evoke a relaxed, elegant, and carefree vibe. Younger fashion lovers are embracing oversized leather bombers, cropped racing jackets, and tailored trenches instead of denim tears jackets. Stylist Lattitia Taylor even advises to 'Marie Kondo' old levis jackets. In 2025, relaxed, loose levis jackets are the go-to style, replacing the unflattering mid-cut versions of the past. The 'Nancy Meyers aesthetic', inspired by Australians dreaming of simple pleasures like fresh-baked croissants and soft cashmere cardigans, has also gained popularity.

The blue levis jacket, once a symbol of youth, is now seen as a sign of age by Gen Z. New trends like the 'Office Siren' and 'Coastal Grandma' looks are emerging, and younger fashion lovers are exploring different styles of outerwear. The shift in levis jacket styles and the rise of the 'Nancy Meyers aesthetic' reflect the ever-changing nature of fashion.
