Some of us just don’t give up the suit, no matter how hot it gets. For them, it’s not just about looking good, it’s about feeling like our best self. So while many of us are reaching for shorts and cranking up the fan, they’re buttoning up and walking through a heatwave like it’s business as usual. Everyone sweats. But looking sharp in summer takes a bit of planning.
The good news is that it’s totally doable. With the right fabrics, breathable layers, and a solid base like sweat-proof undershirts that actually work, you can stay cool and comfortable without giving up your style.
Here’s how to keep things crisp even when the temperature isn’t.
1. Master the Art of Fabric Selection
Staying cool in the summer starts with choosing the right fabric. Even the best-looking suit can feel like a sauna if it’s made from the wrong material. Take Polyester for example. It traps most of the heat and sweat, which is exactly what you don’t want on a hot day.
Then what fabric should you go for? Lightweight, breathable fabrics that help your body breathe and move are your best bet. Here’s some of the fabrics fitted best for summer:
Fresco Wool: This high-twist wool might seem the opposite but surprisingly is breathable and still sharp enough for formal wear. It lets air flow through your suit and pairs perfectly with a moisture-wicking undershirt to keep things fresh.
Linen: Made from flax fibers, linen naturally stands off the skin to let air in. Yes, it wrinkles, but that’s part of the charm. Add a black v-neck sweat-proof undershirt underneath and you're cool, confident, and definitely not crumpled.
Cotton: Cotton suits offer a nice middle ground. For even better comfort, look for cotton-linen blends. They help keep things cool and reduce the wrinkle factor, especially when paired with a sweat-proof shirt made for business days.
Seersucker: That signature puckered texture means less fabric touching your skin and more air getting through. Add a sweat-blocking undershirt underneath and you’re covered, even on the stickiest days.
2. Deconstruct Your Suit’s Lining
Your suit jacket’s lining plays a bigger role in summer heat than you might think. More lining means more heat gets trapped. That’s why choosing a half-lined or quarter-lined jacket, along with a sweat-proof undershirt, can make a huge difference in how you feel throughout the day.
Here’s what to look for:
Half-lined: Offers structure where it counts but keeps the back lighter and more breathable.
Quarter-lined: Even more stripped back. Great for staying cool without losing that tailored look. Just pair it with a solid undershirt designed for suits and you're set.
Unlined or Unconstructed: This is the most minimal option, giving you maximum ventilation. It works especially well with a sweat-proof shirt that’s built to keep you dry and confident.
3. Embrace a Looser, More Relaxed Fit
Give it space: Tight-fitting clothes and high temperatures don’t mix. Your outfit needs room to breathe when it’s hot out.
Wider trousers: These allow for better airflow. Pair them with a moisture-wicking shirt to manage lower back sweat.
Looser sleeves: Roomier shirts keep your arms from becoming sweat traps.
Fit matters: Your suit should skim your body, not cling to it. Aim for that balance between relaxed and refined, especially when layering over a performance dress shirt.
4. Strategize Your Undergarments
Undergarments are your first defense.
Undershirts: Love them or hate them, the right one matters. A Neat undershirt review would tell you: they're not bulky, and they trap moisture with tech so smart it’s practically military-grade sweat shirt level. Whether you're wearing a suit or prepping for a big event, options like the wedding undershirt or office undershirt men swear by are game-changers.
Socks: Go invisible or sock-free. Your ankles will thank you, especially paired with lighter loafers and breathable pants.
5. Optimize Your Shirt Choice
Shirts matter just as much as your suit, especially when the heat kicks in.
Breathable fabrics: Go for materials that let your skin breathe, like cotton-linen blends or Giro inglese weaves. These help keep airflow going and reduce that sticky feeling.
Dress shirt go-tos: For more formal settings, poplins and broadcloths are solid picks. They’re crisp, lightweight, and sit nicely under a blazer without trapping too much heat.
Casual cool options: Those who prefer a casual evening look with t-shirt and a suit combo, neat shirts strike a great balance between style and comfort. If you layer one over a moisture-wicking base shirt, you’ll stay looking sharp even when the temperature’s doing its worst.
6. Smart Accessorizing
Everything you wear should help you stay cool, not make things worse.
Lightweight ties only: Skip the heavy ones unless it’s absolutely necessary. If you need to wear one, go with linen or silk knit for better breathability.
Hats that help: A classic Panama hat isn’t just stylish. It actually keeps your head shaded and cool.
Suspenders over belts: Ditch the belt and let your trousers hang naturally with suspenders. It’s a subtle change that improves airflow and pairs perfectly with a sweat resistant shirt underneath.
Roll it up: Unbutton your cuffs and roll up your sleeves. It’s an easy move that adds ventilation and makes your outfit feel a bit more relaxed.
7. Leverage Color
Color plays a bigger role in heat management than you might think.
Go light: Dark colors absorb sunlight and trap heat, while lighter shades reflect it. That means you’ll stay cooler in pale tones like grey, beige, blue, and cream.
Style meets function: These lighter hues don't just help with temperature. They also give off a clean, fresh look. Try pairing a white polo with a cream blazer for an effortlessly cool vibe.
Layer smart: Add a sweat blocking undershirt underneath to stay dry without sacrificing style. It’s a simple combo that keeps you looking and feeling put together.
8. Strategic Unbuttoning and Layer Management
Use your options: Summer dressing is all about flexibility. Unbutton your jacket while you're on the move and button it back up when it's time to make an impression.
Keep it simple: Skip the vest and lose the extra layers. A tailored two-piece suit over a lightweight, heat-friendly tech undershirt keeps things sleek without the sweat.
Commute smart: If you’re heading into a meeting, carry your suit jacket in a garment bag and wear a breathable base tee for the ride. Change before you walk in and no one will know you were roasting on the train 15 minutes ago.
9. Personal Care and Lifestyle Adjustments
Stay hydrated: Water is your best friend when the heat is on. It helps regulate your body temperature and keeps you feeling fresh.
Eat light: Go for water-rich foods like fruits and veggies. Heavy meals can raise your internal temp and make you feel sluggish.
Shower wisely: A lukewarm shower is better than cold right before heading out. It helps your body adjust to the outdoor heat more smoothly.
Time your antiperspirant: Apply it at night so it has time to activate by morning. This gives you better protection during the day.
Trim underarm hair: This reduces friction and helps your sweat-proof shirts do their job more effectively.
Choose lighter lotions: Heavy creams can trap heat. Opt for breathable, fast-absorbing formulas that won’t weigh your skin down.
10. Practical Tricks for Immediate Relief
Mini USB fan: A small but mighty tool for instant cooling, especially if you're stuck in a warm office or on the go.
Cooling seat pads: These are game changers during long commutes, keeping your back from turning into a sweat zone.
Mint gum: It’s a mental trick, but it works. That cool burst gives you a quick refresh when things heat up.
Backup clothes: Keep an extra sweat-proof shirt in your bag, especially before big meetings. A quick change can save your day and your confidence.
Cool-down rituals: End your day with a cold drink and a lightweight outfit. You’ve earned it.
