September is a transitional month in Southwest Florida. The height of hurricane season lingers, but homeowners also start looking forward to the influx of winter visitors. For many, this is the perfect moment to refresh interiors—before schedules get busier and before homes are filled with family, friends, and returning snowbirds. This September’s design trends reflect a thoughtful mix of warmth, nostalgia, and playfulness. They encourage homeowners to create layered, personalized spaces that feel welcoming and fresh for the upcoming season.
At Interiors by Agostino, we’re seeing more clients lean into bold color, rich textures, and expressive décor as they prepare for the winter months. These trends are not about dramatic overhauls but about thoughtful touches that bring homes to life and set the stage for a cozy yet stylish season ahead.
Welcoming Layers with Velvets and Jewel Tones
After a summer filled with light, breezy fabrics, September brings a desire for more depth and texture. Velvets, chenilles, and heavy linens are moving into the spotlight, paired with jewel tones that instantly elevate a space. Emerald greens, sapphire blues, and garnet reds make their way into accent chairs, throw pillows, and upholstered headboards.
These choices not only add a touch of luxury but also create the kind of layered coziness that feels perfect as evenings get cooler and as more people gather indoors. Jewel tones also complement Southwest Florida’s coastal light beautifully—rich without feeling too heavy. Interiors by Agostino often recommends layering these fabrics with natural textures like rattan or light woods, which keeps the balance between vibrant elegance and relaxed living.
Earthy Warmth with Seasonal Palettes
While jewel tones add drama, the grounding colors of September lean earthy. Shades like butter yellow, deep burgundy, and forest green are gaining popularity. These hues feel warm and inviting, reflecting both fall’s richness and the subtropical palette of the region.
Butter yellow in particular is having a moment—it’s soft, optimistic, and nostalgic, bringing a sense of lightness to kitchens, bedrooms, or dining spaces. Paired with burgundy or green, it creates a balanced backdrop for both traditional and contemporary interiors. Interiors by Agostino has seen homeowners embrace these palettes through accent walls, slipcovered dining chairs, or even decorative accessories like ceramics and rugs. The result is a home that feels seasonally grounded while still flexible enough to transition smoothly into winter.
Rococo Revival and Vintage Maximalism
Nostalgia is running strong in design, and this September, Rococo-inspired flourishes are making a comeback in a modern way. Delicate curves, ornate mirrors, and sculptural furnishings are being paired with contemporary elements to create spaces that feel layered and expressive. It’s not about going full 18th century—it’s about introducing a touch of whimsy or elegance that feels collected over time.
Maximalism is also influencing this revival. Instead of pared-back minimal spaces, homeowners are adding character through gallery walls, patterned textiles, and vintage finds. Interiors by Agostino often helps clients source pieces that bridge the gap between historical inspiration and modern function. A vintage-inspired chandelier over a sleek dining table, for instance, creates a conversation piece that embodies this blend perfectly.
Sustainable Choices and Thrifted Finds
Another trend shaping September interiors is sustainability. As more homeowners seek meaningful design, thrifted and repurposed finds are stepping into the spotlight. Antique stores, estate sales, and even salvage markets are being scouted for unique treasures. From hand-carved sideboards to retro tile accents, these pieces tell stories while adding authenticity to interiors.
This focus on sustainability also extends to materials. Natural stone, reclaimed wood, and recycled textiles are making their way into furniture and décor choices. Interiors by Agostino encourages clients to combine these thrifted or sustainable elements with new, custom pieces to create interiors that are both environmentally conscious and deeply personal. The combination of old and new makes spaces feel intentional and layered, perfect for impressing snowbird visitors with something unexpected and fresh.
Expressive Decor with Sculptural and Playful Touches
Finally, September 2025 is all about having fun with décor. Sculptural pieces, whether they’re ceramic vases, geometric lighting fixtures, or asymmetrical mirrors, are being used as focal points. These pieces add personality and artistry, turning everyday objects into statements.
Playful maximalism is also trending, with bold patterns and vibrant art pieces finding their way into living rooms and bedrooms. Homeowners are embracing more personal expression, moving away from neutral-only spaces to interiors that reflect their unique stories. At Interiors by Agostino, we’ve found that even small touches—like a colorful accent chair or a whimsical rug—can shift the entire mood of a room and make it feel lively and welcoming.
Why September Is the Perfect Time for Change
With snowbird season right around the corner, September offers a unique window for homeowners. It’s the calm before the winter social season begins, making it the ideal time to tackle updates both big and small. Whether it’s reupholstering a set of chairs, refreshing the color palette, or introducing a few thrifted treasures, these changes create a welcoming environment for the months ahead.
Interiors by Agostino often recommends this timeframe for clients who want to be ready for entertaining, holiday gatherings, and seasonal guests. By making updates now, homeowners can enjoy the season without the stress of last-minute design changes once their homes are filled with family and friends.
Balancing Timelessness and Trend
One of the most rewarding aspects of September’s design trends is their flexibility. While jewel tones and Rococo-inspired flourishes might feel bold, they can be layered into interiors in ways that still feel timeless. A butter yellow wall can be softened with neutral furniture. A vintage chandelier can coexist with streamlined modern pieces. Sculptural accents can be swapped seasonally for a quick refresh.
At Interiors by Agostino, we believe in helping clients strike this balance—embracing what’s trending while grounding it in classic design choices that will last for years. This approach ensures that your home not only feels current for the season but also evolves gracefully over time.

From velvets and jewel tones to sustainable thrifted finds, from Rococo-inspired elegance to playful maximalism, the trends of September 2025 encourage homeowners to express themselves while creating spaces that are layered and inviting.
