This season’s menswear trends blend practicality and personality, mixing sharp tailoring, relaxed silhouettes and thoughtful layering that you can build with what’s already in your closet. It’s a reminder that sustainable fashion is the future, by styling smarter, choosing better and resisting the constant churn of trends.

While winter coats and formal jackets have always been cold weather staples, 2025 brings a twist. Menswear is leaning into oversized fits, relaxed tailoring and reworking 2000s layering. Think long sleeved tops underneath tees, hoodies underneath leather jackets and shirts worn over basics. This makes sustainable fashion trends easy and effortless, it’s all about reworking what you already own, choosing versatile pieces and supporting sustainable fashion brands that create for longevity.

As conversations around ‘how sustainable is the fashion industry’ continues to rise, this season shows that style and sustainability don’t have to compete. With these fashion trends, you won’t have to buy new but think about styling and rewearing cold weather staples you already have in your closet.

Winter 2025 proves that sustainable fashion is the future, by looking sharp and staying warm, whilst building a closet that makes sense for both your style and the planet.

Puffy, balloon fit

Baggy style has been a go-to all year round, but winter 2025 takes the trend further with the rise of the balloon fit. Think baggy, but a softer and more intentionally voluminous fit. This puffy shape brings comfort into the spotlight whilst still feeling stylish.

A simple puffer jacket instantly taps into this look, low-effort, high impact and with effortlessly cool energy. It gives the energy that you didn’t even have to try, and you still look good. Pairing a puffer jacket with wide-leg or baggy jeans keeps the silhouette balanced and leans into the casual and street-ready vibe.

It’s practical, warm and easy to style with pieces you already have, a win for both fashion and sustainability.

Corduroy

Corduroy is having a moment this winter. From subtle detail like a corduroy collar, to full structured corduroy jackets, this fabric is the perfect bridge from autumn to winter. It adds warmth, texture and a slight retro edge without feeling too heavy.

Corduroy is one of those pieces that naturally fits into sustainable fashion trends because it lasts, softens beautifully over time and pairs effortlessly with basics already in your closet. It’s a reminder of why sustainable fashion is important. Investing in durable materials means less replacing and more rewearing.

Co-ord sets

Co-ords aren’t going anywhere, especially for menswear this winter. Matching sets create that clean, intentional look with zero styling effort required. They’re polished without being overly formal.

The beauty of co-ords is that they fit perfectly into sustainable fashion habits. Two pieces, endless mix-and-match fits. A simple way to reduce over-buying while still refreshing your style, which is why sustainable fashion is the future.

Leather jackets

Leather jackets are officially back in the spotlight, but more oversized, relaxed and wearable than ever. Think 90s style, slightly boxy, thrown over a hoodie.

If you’re trying leather this season, consider vintage or second-hand pieces. Not only is it smarter financially, but it’s also exactly what sustainable fashion means: choosing longevity over constant newness. High-quality leather lasts decades, not seasons.

Oversized coats

Oversized coats are everywhere, bringing sophistication and structure to even the simplest outfit. It’s the quickest way to look put-together with zero effort.

The shift towards one amazing statement coat instead of multiple micro-trend jackets is what sustainable fashion means, focusing on high-quality outerwear that lasts.

Intentional layering

Layering isn’t just practical this year, it’s the biggest style trend. Long sleeves under graphic tees and hoodies under leather jackets. It’s so early 2000s, except elevated for 2025.

This is one of our favourite sustainable fashion trends as it uses what you already have, no purchases needed. Just thoughtful layering that adds dimension, warmth and personality. This proves why sustainable fashion is important, you don’t need more clothes to create more outfits.

The best part about Winter 2025’s fashion trends is that you don’t need a whole new wardrobe to take part. Most of these looks come from intentional styling, smart layering and choosing pieces that will last, exactly what sustainable fashion means in a practical way.

If you’re ready to make your closet more versatile and sustainable, start with what you already have, thrift, borrow from friends or swap with CloSh. Small changes make a big impact.
