Summer 2025 Men’s Lookbook: Shorts, Linen & Retro Cool
Dressing for summer can be a bit of a puzzle. Too casual and you're underdressed. Too buttoned up and you’re melting by lunchtime. That’s where a curated lookbook comes in; instead of just throwing on a pair of shorts and hoping for the best, you’d be able to find the perfect warm-weather pieces that look sharp, feel cool, and align with your summer 2025 plans.
At Sirri, we’ve put together the biggest summer 2025 menswear trends and refined them into wearable outfits you can actually see yourself in. Whether you’re headed to a garden party, weekend getaway, or a beach wedding, this guide has you covered. Keep scrolling for outfit inspiration and style tips to level up your wardrobe right now.

Summer 2025 Trends You’ll Actually Want to Wear
The Rise of Short Shorts
Say goodbye to the knee-length cargo shorts of your teenage years. Summer 2025 is officially the season of short shorts for men. Now, you have tailored cuts that show off a bit of thigh in a classy way. Pair them with loafers or boat shoes, and you’ve got a crisp Riviera vibe going on.
Linen Everything
Breathable, light, and always refined, linen is a summer staple—and for good reason. This year, it’s all about relaxed linen blazers, tailored trousers, and co-ord sets in pastels, stone, and sandy beige. Whether you go for a full matching set or mix linen separates with cotton basics, the result feels effortlessly cool. Our new summer arrivals feature several standout linen pieces that make staying sharp in the heat a breeze, like our lightweight men’s linen blazers collection.
Printed Shirts with Personality
Florals, botanicals, nautical stripes, and abstract shapes—summer printed shirts for men are having a moment. But, we’re not talking about the loud Hawaiian styles. The take of summer 2025 is more polished and wearable. Try an open-collar floral shirt layered over a fitted white tee or buttoned up with tailored shorts. For a night look, tuck one into tailored trousers and roll up the sleeves.
Footwear and Accessories That Do the Heavy Lifting
The small details are doing a lot of the work this year. Boat shoes are officially cool again. Flip-flops and sliders are getting a minimalist makeover. And accessories like rimless sunglasses, beaded bracelets, and even lightweight chains are showing up in stylish ways. It’s the easiest way to take a simple outfit and make it feel intentional.
Retro Is Back and It’s Fun
Designers are bringing back playful nostalgia with polo shirts, textured knits, schoolboy motifs, and subtle brooches. You don’t need to go full costume to try this trend. Just a retro knit with a relaxed trouser or a single vintage accessory can pull in the vibe without feeling forced.
Loose Fits and Plaid
If you’re not into short shorts or slim cuts, good news. Relaxed tailored trousers, bootcut denim, and check patterns are very much in rotation in summer 2025. Plaid trousers with a crisp tee or an oversized short-sleeve shirt gives you that laid-back look while keeping things stylish.
A Shift Toward Quiet Luxury
Minimalist palettes, natural fabrics, and timeless pieces are winning out over flashy fast fashion. More men are focusing on quality rather than quantity by purchasing fewer items. Think clean tailoring, neutral tones, and pieces that last beyond one season. And that’s precisely what we’re all about at Sirri: offering you style that speaks quietly but confidently.
