4. Avoid Wearing Denim on Denim

The so-called “Canadian tuxedo” is back in style, with celebrities and designers proudly embracing denim-on-denim looks. Modern fashion icons are layering jean jackets with denim shirts and jeans, creating dynamic, statement-making outfits. The key to mastering this trend is mixing different washes and fits—pair a light-wash jacket with darker jeans or experiment with oversized and tailored silhouettes for added dimension. Recent celebrity ensembles have proven that denim on denim can look effortlessly cool and contemporary. For expert tips and inspiration, check out GQ’s denim layering guide.

5. Sequins Are Only for Night

The belief that sequins are strictly reserved for evening events has been turned upside down. Designers and trendsetters are now incorporating sequins into daytime looks, from shimmering blazers paired with jeans to sequin skirts styled with cozy sweaters. Fashion week street style galleries are full of dazzling day-to-night ensembles that prove sparkle belongs anytime. Mixing sequins with casual pieces adds a playful, modern edge to everyday wear.

6. Stick to Flattering Silhouettes Only

The notion that you must always wear what is traditionally “flattering” is fading fast. Oversized and unconventional silhouettes—like boxy blazers, wide-leg trousers, and voluminous dresses—are now celebrated for their artistic expression and comfort. Designers are championing experimental shapes that defy outdated beauty standards, empowering everyone to dress as they please. This movement supports body positivity and inclusivity, allowing personal style to take center stage over societal expectations.

Major brands like Prada have featured this pairing on the runway, while influencers across the globe are styling colorful socks with everything from sporty slides to chunky sandals. This look brings comfort and personality to any outfit, challenging the boundaries of conventional styling. The playful mix of textures and prints adds interest and individuality.

8. Age Determines Your Style

The outdated belief that style choices should be dictated by age is being replaced by a celebration of ageless fashion.

Major brands are featuring models and influencers from a wide range of age groups, highlighting the beauty and individuality of every generation. This shift encourages everyone to experiment with trends, regardless of age.

9. Men Should Avoid Bold Colors

The old-fashioned idea that men should stick to muted tones is rapidly disappearing. Designers and celebrities are embracing bold colors, from vibrant pinks and electric purples to striking neons, on both runways and red carpets. This shift not only adds excitement to menswear but also encourages self-expression and confidence. According to GQ’s analysis of men’s fashion trends, bold hues are now a staple in contemporary collections, challenging traditional gender norms and making menswear more dynamic than ever before.

10. Logos Should Be Subtle

The minimalist approach to logos has given way to a vibrant resurgence of logomania. Brands such as Louis Vuitton and Balenciaga are leading the trend, showcasing bold, oversized logos on bags, apparel, and accessories. These statement pieces are embraced by fashion lovers as symbols of confidence and brand affinity, rather than something to downplay. Wearing visible logos is now seen as a celebration of style and identity. To learn more about how logomania is shaping the current fashion landscape, read Business of Fashion’s analysis on the return of logos.

11. Formal and Casual Clothes Don’t Mix

The boundary between formal and casual wear is becoming increasingly blurred in today’s fashion scene. Mixing tailored blazers with sneakers, or pairing joggers with crisp button-down shirts, is now a celebrated way to showcase versatility and personal flair. This high-low combination is embraced by designers and street style enthusiasts alike, offering countless ways to refresh classic pieces. The result is a look that’s both relaxed and polished, perfect for any occasion. For more ideas and styling tips, check out Esquire’s guide to mixing formal and casual menswear.

12. Fashion Is Only for the Runway

The belief that fashion belongs exclusively to the runway is outdated. Today, style is accessible and deeply personal, thriving in communities, on social media, and across city streets. Street style, upcycling, and DIY trends empower individuals to create unique looks outside high fashion circles. Everyday people are now trendsetters, influencing designers and brands with their creativity and authenticity. This democratization of style proves that fashion is for everyone, not just industry insiders.
