What to Wear to the Office in Summer: The Ultimate Men’s Style Guide

There is a specific type of pain that comes with commuting into work during an Aussie summer. You step out the front door at eight in the morning, the humidity smacks you in the face, and by the time you reach your desk, you’ve sweated through your shirt before the workday has even started. Worse yet, once you step inside the building, the commercial air-conditioning is routinely cranked to arctic temperatures, leaving you freezing in your own damp clothes for the next eight hours.

With some parts of Australia set to experience its hottest weather in years, we can only guess what the summer months might bring. And so, we’re getting in early with our guide to what to wear to the office when it’s hot as heck outside. From the bottom to the top, these are wardrobe staples to make sure you survive the heat this summer (and look effortlessly stylish while doing it). 

Men’s Summer Office Wear: What to Wear From the Feet Up

Footwear & Socks: Airflow Meets Dress Code

The biggest mistake guys make when the mercury spikes past 35 degrees is sticking with the same leather dress shoes and thick ribbed socks they wore all winter. Trapping your feet in thick leather and heavy cotton socks is a fast track to overheating before you even reach the train station.

However, how you approach summer footwear comes down to how strict your office dress code is.

For creative and smart casual offices, you can lean into footwear designed for airflow. Woven or braided leather loafers are ideal because the tiny gaps in the leather weave act like built-in air-con while still holding the sharp shape of a shoe. Suede mules or canvas slip-ons also work really nicely, giving you a clean look from the front while letting your feet breathe.

For stricter corporate dress codes (looking at you, law and finance), sorry to say, you’re just going to have to tough out real leather. There’s no way around it. Your best bet here is picking a lighter leather penny loafer over a heavy lace-up Oxford, and then choosing the right socks. 

No-show socks are essential if you’re wearing loafers in a casual office. If you’re in a corporate environment that demands long dress socks, swap heavy ribbed cotton for fine merino wool or bamboo. Wool sounds hot, but thin merino is a natural temperature regulator that wicks moisture away instantly so your feet aren’t sitting in sweat all day.

Summer Trousers & Chinos: Ditching Tight Fits

Skin-tight tailoring and intense humidity can be a particularly toxic combination. When your pants cling to your thighs, sweat has nowhere to go, and air can’t circulate. Summer trousers should give your legs room to breathe while still maintaining a professional drape.

Single or double-pleated trousers are perfect for this time of year because the extra fold of fabric at the waist gives you plenty of room through the hip and thigh, which also means extra comfort when you’re sitting at a desk all afternoon.

In terms of material, look for linen-cotton chinos, which offer the structured look of a traditional work pant with the lightweight chill of linen. 

Another massive upgrade is swapping rigid leather belts (which trap heat directly around your waist) for trousers featuring side-adjusters or a flat-front drawstring.

Shirts & Polos: Open Collars and Breathable Knits

When it comes to tops, your shirt is your first line of defence against visible sweat patches, so we’d suggest putting most of your focus on the cut and the collar.

A short-sleeve camp-collar shirt in a solid, muted tone like navy, dark olive, or off-white is perfect for heatwave dressing. Because the collar sits flat against your collarbone, it leaves your neck open to catch a breeze while still looking office-appropriate when tucked into tailored trousers. 

If you want something with a bit more texture, open-knit or crochet-style polos offer infinitely more airflow than a standard jersey tee while looking vastly more refined.

And for those truly scorching days, nothing beats a slightly oversized linen button-down with the sleeves rolled twice up the forearm.

Layering for the Office Air-Con: Blazers & Light Knits

As any Australian office worker knows, the real trap of Australian summer office life isn’t simply the sun outside, it’s the aggressive air-conditioning waiting for you inside. Dressing purely for the outdoor temperatures means you’ll be shivering at your computer by midday.

The trick is carrying a layer you can throw on the moment you walk into your office.

An unlined linen blazer without shoulder padding or interior lining feels as light as a shirt, but also checks the corporate box. 

If your office is more casual, a cotton or linen chore jacket serves the exact same purpose. Alternatively, you could simply keep a neutral fine-gauge crewneck sweater at the office as your insurance for the days the AC gets kicked into overdrive.

Failproof Men’s Summer Office Outfits (From Creative to Corporate)

1. Creative & Tech Offices: Relaxed Linen & Smart Sandals

The Fit: Oversized linen button-down + relaxed chinos + leather sandals 

If your workplace doesn’t care about ties or tailoring, this is your summer staple outfit. An oversized linen shirt worn untucked with the sleeves rolled twice gives you maximum airflow while still looking polished. Pair it with relaxed cotton chinos and complete the look with leather sandals. Also, keep an unlined cotton chore jacket hanging on your chair to throw over the shirt for when the AC is on. 

2. Smart-Casual Offices: Open-Collar Shirts & Suede Loafers 

The Fit: Short-sleeve open-collar shirt + single-pleat trousers + suede loafers 

This outfit hits the sweet spot for modern agencies, tech offices, and casual Fridays. An open-collar or camp-collar shirt in a patterned colour looks very cool when paired with single-pleat trousers. The pleats give your hips and thighs breathing room, while the suede loafers keep your feet cool without showing a hint of toe. 

3. Modern Professional Offices: Unstructured Blazers & Tailored Trousers

The Fit: Open unstructured blazer + premium tee + lightweight wool trousers + leather penny loafers

If your office expects tailoring but you can’t stomach a full suit in thirty-degree heat, swap out a stiff button-down for a thick, good-quality white tee. Sitting under an unstructured blazer, it keeps your neck cool and feels way lighter while still looking professional. Match it with wide, double-pleated trousers so air can circulate around your legs, then throw on black penny loafers and dark sunnies.

4. Corporate & Finance: Light Linen-Blend Suits & Leather Loafers

The Fit: Unstructured wool or linen suit + lightweight linen shirt + leather dress loafers

If you still need to suit up, leave the heavy padded shoulders and lining in your winter wardrobe. Instead, go for an unstructured suit in a breathable blend (cotton-linen or wool). If you’re allowed, nix the tie and instead leave the top button of a lightweight oxford shirt undone for some airflow. Then, finish with leather dress loafers worn with no-show socks.

Summer Fabric Guide: What Materials Keep You Cool?

If you take only one piece of advice away from this entire guide, let it be this: always check the fabric tag. Synthetic materials like polyester, nylon, and acrylic act like plastic wrap, trapping heat and moisture directly against your skin until you’re practically baking in your own clothes. You want to build your entire summer wardrobe around open-weave, natural fibres that allow air to pass through freely.

• Linen: The undisputed fabric champion of summer. Linen absorbs moisture and dries in minutes. And the best part is that the natural, slightly rumpled texture is part of its charm, so not intense ironing required. 
• Tropical wool: Woven with an open, airy construction, tropical wool is surprisingly light, naturally wrinkle-resistant, and regulates temperature a lot better than any synthetic blend.
• Cotton-linen blends: This gives you the best of both worlds. The breeziness of linen paired with the opaque structure and crease-resistance of classic cotton.
• Seersucker: Recognisable by its signature puckered weave, seersucker fabric sits slightly off the skin rather than flush against it, creating tiny internal air channels that keep you nice and cool.

Choosing the Right Colour Palette for Your Summer Wardrobe

Managing heat in the workplace is as much a visual strategy as a physical one, and the colours you choose play a huge role in both absorbing heat and hiding sweat.

While logic suggests wearing light colours in summer, flat light grey and pastel blue are notorious for showing sweat marks under the arms and across the back. Instead, lean into dark neutrals like deep navy, black, dark olive, and rich chocolate brown, because darker shades hide sweat instantly. 

For trousers and jackets, lean into earthy mid-tones like stone, sage, terracotta, and tan. They’re inherently summery without looking like you’re wearing beachwear to a board meeting.

Beat the Commute: How to Avoid Sweating Through Your Work Shirt

Beating the summer heat doesn’t just come down to what you wear but also how you navigate the commute. A few adjustments and some forward thinking can absolutely save your outfit before you reach your desk:

• Strapping a heavy backpack across your shoulders when it’s boiling outside is a guaranteed recipe for a sweat-soaked back. Swap it for a leather or canvas tote carried by hand or slung over one shoulder to keep your shirt dry.
• If your commute involves a packed train or a long walk in direct sun, wear a basic cotton tee for the trek. When you arrive at the office, swap into your freshly pressed work shirt.
• Keep a chore jacket or fine-gauge knit permanently draped over your desk chair. That way, you’re always covered when your office aircon is on full blast.
