Key Elements of Oversized & Retro Athleisure

Oversized and retro athleisure has become a defining fashion trend in 2025, merging streetwear aesthetics with everyday comfort. At the core of this look are oversized tees and hoodies, often styled in boxy, drop-shoulder silhouettes and sized up one or two sizes for that effortlessly cool, slouchy vibe. Popular labels like PERKS Liftwear, Moda Knits Apparel, and House of Colour highlight how these relaxed fits dominate the streetwear and athleisure fashion market. Completing the look are baggy pants and trackpants—from wide-leg track pants to cargos and parachute trousers—that offer breathability and ease of movement, reflecting the sportswear-meets-streetwear culture praised by Athleisure Mag™ and other fashion outlets.

Layering is another signature of retro athleisure fashion, with vintage-inspired track jackets and bomber jackets styled oversized over tees or even dresses, giving a nostalgic throwback while maintaining versatility. The bold edge comes from logo-heavy designs and statement prints—think bright colors, retro lettering, neon accents, and ’90s graphic patterns—that inject playful energy into casual street style. Brands like Tack Apparel and PERKS Liftwear continue to spotlight these standout pieces in their collections. Finally, a major driver of this trend is the focus on unisex and gender-neutral fits, offering versatile boxy tees, oversized jackets, and relaxed silhouettes that appeal to all genders, breaking away from traditional fashion boundaries while reinforcing inclusivity in the global athleisure market.
