Interior designers share the 9 living-room trends that missed the mark this year

Kristina Phillips, an interior designer at Kristina Phillips Interior Design, doesn't advise designing spaces based on current styles, including "Barbiecore."

"Inspired by the Barbie movie hype, the 'Barbiecore' trend brought bubblegum pink into living spaces. However, like cotton candy, this look now feels dated and overly sweet," she told Business Insider.

From curved couches to arched windows and doorways, curvy accessories have become a recent big hit.

But Phillips warns that too many curved pieces can add chaos to living-room spaces.

"While a single sofa or a pair of chairs with a free-form design can be elegant, an entire room filled with shapeless, curvy pieces may start to look like an amusement park," she told BI.

The "grandmillennial" style — sometimes called "granny chic" — combines modern aesthetics with older design trends.

According to Phillips, it's a style that can quickly become messy.

"Skirted tables, slip-covered sofas, and fully upholstered chairs are all trademarks of the grandma chic fad. This excessive use of fabric can be overwhelming and messy," she said.

Although many prefer neutral colors in their living room for a clean, aesthetically pleasing look, interior designer Rudolph Diesel told BI that the trend isn't always a good idea.

Monochromatic neutral color palettes can "take away from the depth" of a space.

"So instead of a cool or streamlined appearance, monochromatic schemes can seem unimaginative and dull," Diesel said.

Rattan furniture is a great way to spruce up a boho-style living room, but too much of it can get overwhelming.

"Most people love a good bohemian design, and rattan furniture is an excellent way to showcase and complement this look," Diesel said.

"However, too much rattan — think rattan armchairs, side tables, shelves, and hutches— can hint at a lack of imagination and material overwhelm."

Interior designer Soledad Alzaga said terrazzo flooring — a composite with chips of marble, quartz, granite, and glass to give it a speckled look — is not a good fit for living spaces.

"It's an expensive material to install well. It's not versatile, cold to the touch, slippery, and very permanent," they said.

Open floor plans have been popular but they just aren't practical, said Artem Kropovinsky, an interior designer and founder of Arsight.

"The trend of completely knocking down walls for an expansive living space ignores the human need for coziness and the practicality of noise reduction and energy efficiency in compartmentalized spaces," he told BI.

Loved for its clean and minimalistic look, all-white living rooms can feel too sterile, according to Joyce Huston, the lead interior designer and cofounder at Decorilla Online Interior Design.

"This year, clients craved more color and personality in their living rooms as a form of self-expression," Huston said.

She's seeing more people request vibrant reds, oranges, blues, and magentas.

Huston told BI that warmer, cozier spaces are winning favor over bare, minimalist ones.

"While minimalism did its rounds in the past few years as a chic trend, it can feel cold and uninviting," Huston told BI.

She said she's seeing more clients add layers of texture and color to their rooms to create warm, inviting spaces. Some of them are even opting for maximalist looks.
