Seasonal Style Guide: What to Wear This Spring & Summer

As the weather warms up, getting dressed should feel easy — lighter layers, breathable fabrics, and versatile pieces that work across your day. Spring and summer are the perfect seasons to refine your wardrobe with timeless staples that look good, feel comfortable, and last beyond one season.

This guide breaks down how to build effortless spring and summer outfits while keeping sustainability at the core of your style choices.

Start with a Versatile Button-Down

A well-made button-down shirt is one of the most important pieces in a warm-weather wardrobe. It works for casual days, travel, dinners, and even relaxed office settings. Look for breathable fabrics like organic cotton, which offer softness and airflow without sacrificing structure.

The Alta Button-Down Shirt is a strong foundation piece for spring and summer. Its clean lines and lightweight feel make it easy to wear tucked or untucked, buttoned up or layered over a tee. Pair it with chinos for a polished look or shorts for a more relaxed, warm-weather outfit.

Neutral tones work especially well this time of year, allowing you to rotate the same shirt across multiple outfits without feeling repetitive.

Layer Smart for Cool Mornings and Evenings

Spring weather can be unpredictable, and summer nights often cool down faster than expected. Instead of reaching for a bulky jacket, an overshirt offers the perfect balance of warmth and flexibility.

The Boulder Haven Overshirt is ideal for transitional weather. It layers easily over a button-down or t-shirt and adds texture without feeling heavy. Wear it open during the day or buttoned up at night for a slightly more refined look.

This type of layering piece is especially useful when traveling — one item that works across different temperatures and settings.

Easy Daytime Outfits

For everyday wear, simplicity is key. A breathable button-down paired with lightweight pants or tailored shorts creates a look that feels intentional without trying too hard.

Try this formula:

• Alta Button-Down Shirt

• Neutral chinos or linen trousers

• Low-profile sneakers or loafers

This combination works for brunch, casual meetings, or weekend errands while keeping you cool and comfortable.

Day-to-Night Transitions

The best spring and summer outfits are the ones that don’t need to be changed halfway through the day.

• Day: Button-down with rolled sleeves, lightweight pants, sneakers

• Night: Add the Tahoe Overshirt, swap sneakers for loafers or boots

With just one added layer, your outfit instantly feels more elevated.

Why Fabric and Construction Matter

Warm-weather dressing isn’t just about style — comfort plays a huge role. Sustainable materials like organic cotton are naturally breathable and softer on the skin, making them ideal for longer days and higher temperatures.

Choosing well-made pieces also means fewer replacements over time, which is better for your wallet and the environment.
