What colors to wear in hot weather: stylist's advice

Every summer, fashion magazines and influencers repeat the same mantra: "Wear only light colors in hot weather." But have you ever wondered why the Bedouins of the Sahara Desert have been draping themselves in black and dark blue layers for centuries? When clients ask me, What colors of clothes should I wear in hot weather? , my answer often raises eyebrows. I advise them to put aside their thin white sundresses and consider deep navy, emerald, and even burgundy.

My name is Julia Rossi, and after 12 years of working as a stylist at European resorts, I've learned one important thing: the mass market sells us illusions. Choosing the right shade for the scorching sun isn't just a matter of aesthetics; it's pure physics and health considerations. We've already covered the basic principles of a summer foundation in more detail in our The complete guide to modest summer fashion: how to dress stylishly in the heat , and today we’ll talk exclusively about the magic of color and texture.

What colors to wear in hot weather: debunking the biggest mass-market myth

A common misconception is that white protects against overheating because it reflects the sun's rays. This is true. But there's a physical paradox here that stylists rarely discuss. White fabric reflects heat not only outside , but also from the inside.

Your body constantly radiates heat (around 37°C). When you wear white clothing, it reflects this heat back to your skin, creating a greenhouse effect. Dark colors, on the other hand, absorb your body heat.

In a classic study published in Nature in 1980, physicists measured the temperature under the black and white robes of Bedouins in the desert at 45°C. It turned out that the skin temperature under the black robe was exactly the same as under the white one. The secret lay in convection.

Black or dark blue fabric heats up in the sun, creating a temperature difference. If the clothing is loose (such as a kaftan or wide palazzo pants), the hot air rushes upward, exiting through the collar, and draws in fresh, cool air from below. This creates a chimney effect, providing constant ventilation and cooling to the body.

One of my VIP clients in Capri suffered for years from sun allergies and overheating, stubbornly buying white, sheer dresses. When I persuaded her to try a one-piece suit with palazzo pants in midnight blue, she was able to walk comfortably at midday for the first time. This secret has long been used by fans of "quiet luxury"—regulars of the Riviera and Forte dei Marmi—who increasingly choose dark, yet covered and loose-fitting silhouettes for the midday heat.

UPF Rating: Why Dark Shades Are the Best Investment in Youthful Skin

A tan is no longer a status symbol. Wealthy women today invest heavily in maintaining porcelain skin. And here, the indicator UPF (Ultraviolet Protection Factor) — index of fabric protection from ultraviolet radiation.

According to the Skin Cancer Foundation, a typical white cotton T-shirt has a UPF rating of about 5. This means it lets up to 20% of harmful UV rays pass directly to your skin. If the fabric gets wet from sweat or pool water, this rating drops to UPF 3. You literally tan through your clothes.

Now compare: the same T-shirt, made from the same cotton, but dyed dark blue or emerald, provides UPF 50+ protection. Dark dyes contain pigment molecules that actively absorb UV rays before they reach your body.

• Light and thin fabric: allows UVA and UVB rays to pass through, causing photoaging.
• Dark and dense fabric: Works like a physical screen, better than the most expensive sunscreens.

Modest, covered fashion in rich tones isn't just an aesthetic choice; it's a powerful anti-aging strategy. By investing €150–€200 in a quality shirt in the right shade, you can save thousands of euros on cosmetic procedures to remove pigmentation in the fall.

An elegant palette for the scorching sun: top status shades

Ditching an all-white wardrobe doesn't mean switching to mournful black. In the summer collections of premium brands like Loro Piana and Brunello Cucinelli, we see sophisticated, elegant colors that look incredibly expensive in the bright sun.

Deep blue (Navy) and rich emerald

It's the perfect alternative to black. Navy looks softer, doesn't create a sharp contrast with the face, and stunningly complements both a light golden tan and an aristocratic pallor. Unlike black, blue and emerald don't fade as quickly in the sun and perfectly conceal any traces of sweat—a critical factor on hot days.

Terracotta, burgundy and wine

Did you know that shades containing red pigment have phenomenal UV blocking properties? Research shows that red and burgundy absorb UV rays almost as effectively as black. These traditionally "fall" colors create a surprising element in a summer cruise wardrobe. A wine-colored maxi dress in flowing silk against the azure sea always draws admiring glances.

Correct white: when is it appropriate?

I'm not suggesting you throw out all your white clothes. But if you choose white for a daytime walk, follow two strict rules. First, the fabric should be tightly woven (heavy linen over 160 g/m² or thick cotton). Second, the cut should be extremely oversized. Only a large volume of air between the fabric and the body will compensate for the heat return we discussed above.

Material Matters: Why the Right Color Doesn't Work on Cheap Fabric

My advice to wear navy blue in summer has one critical limitation: This doesn't work with synthetics at all. Even the most noble emerald shade will turn into a torture chamber if the item is made of polyester.

The physics of convection require fabric to "breathe." If the fibers don't allow air to pass through, the hot air will simply be trapped inside, causing heatstroke. Here's how premium fabrics in dark colors perform:

1. Natural silk: It has a natural cooling effect. Dense, flowing silk (tulberi), weighing at least 19 momme, is opaque, protects against UV rays, and glides over the skin, leaving a cool sensation.
2. Heavy flax: Unlike thin, translucent cambric, dense suit linen holds its shape and creates an ideal “chimney” for ventilation.
3. Viscose cupro (Cupro): An eco-friendly material, often referred to as "vegan silk," it wicks away moisture and shimmers gracefully in the sun.

Stylist's advice: Before purchasing a summer item, always test the fabric against the light by holding it up to a lamp or window. If you can clearly see the outline of your hand through the fabric, the UV light will also pass through. Save such items for evening wear, and choose opaque fabrics for active sun exposure.

The Art of Combinations: How to Mix Summer Colors to Look Expensive

Color only works in the right context. When creating summer looks for my clients, I rely on the principle of monochrome and thoughtful contrasts.

Monochrome looks in rich, dark tones are the ultimate signature of the "quiet luxury" style. A loose-fitting pantsuit in olive or deep blue looks far more classy than a colorful floral dress. It's the perfect choice for a business lunch on a restaurant's outdoor terrace or a Friday-night dress code at the office.

If monochrome seems too stark, try color blocking. For example, terracotta wide-leg pants paired with a navy silk top. To ensure such subtle combinations are easy to pull off, I recommend my clients use MioLook You simply upload photos of your items into the app, and the AI stylist will suggest dozens of combinations of complex shades you might not even have imagined.

Don't forget about the fittings and accessories. Chunky gold jewelry looks fantastic against terracotta and wine-colored backdrops, while natural baroque pearls make dark blue linen glow from within. Dark chocolate-colored leather sandals (around €100–€150 in the mid-range) will complete a classy look better than standard black or white sandals.

Checklist: Building a Closed Status Capsule for Hot Climates

It's time to reassess your summer wardrobe. Ditching micro shorts and tight tops in favor of elegant modesty is an investment in your health and style.

Here's a step-by-step shopping plan to create the perfect summer capsule:

• Linen palazzo pants in dark blue. Choose styles with pleated waists and wide-legs. Expect to spend €120–€250 for a quality piece.
• Men's cut silk shirt in emerald or burgundy shade. Wear it open over a light top or tied in a knot at the waist.
• A-line maxi dress. Avoid fitted styles. Air should circulate freely from the hem to the collarbone.
• Accessories made of natural straw (raffia). A wide-brimmed hat and a woven tote bag add texture and break up the density of dark fabrics.

Of course, when choosing rich colors, it's important to consider your complexion. If deep burgundy seems too heavy on your face, tone it down—buy burgundy pants, and brighten up the portrait section with an ecru top.

Forget the "only light clothes in summer" rule. Choose at least one loose-fitting piece of high-quality dark linen, wear it on the hottest day, and you'll physically feel the cooling effect. This is when science and high fashion combine to give you impeccable comfort.
