From Martha Stewart’s Parties to Chanel’s Runway: How Celestial Decor Is Set to Become the Biggest Interior Trend of 2026

,It's the runway show that everyone's been talking about – Chanel's spring/summer showcase in Paris recently has everyone buzzing with excitement about the clothes, yes, but also the mesmerizing planetary set design.

Martha Stewart has even chimed in, posting photos of an outer space-inspired birthday party set-up to her Instagram page shortly after the show. With shades of whimsigoth, might this signal a celestial interiors trend? We think yes.

While inflatable planets are not the most practical for the home, we're taking cues from Martha and Chanel in the realm of celestial aesthetics; and designers agree that it's a trend to look out for as we enter 2026.

According to design experts, the groundbreaking Chanel show is not only determining clothing trends for the next season, but also how we decorate our homes.

'This season’s planetary-themed runway looks have everyone looking up, and we’re seeing that same fascination reflected in how people are decorating their homes,' explains Dayna Isom Johnson, trend expert at Etsy.

'Shoppers are inviting something more imaginative and expansive into their spaces, reaching for celestial motifs, iridescent finishes, and cosmic color palettes that feel truly out of this world.'

Dayna tells us that decor options range from obvious outer space motifs to more subtle silhouettes.

'On Etsy, we’re noticing more shoppers drawn to pieces that capture the magic of the night sky, think moon-shaped mirrors or galaxy-inspired ceramics,' she tells us. 'Whether it’s a velvet cushion embroidered with constellations, hand-poured candles with metallic flecks, or wall art inspired by lunar phases, this trend celebrates creativity, optimism, and our connection to something bigger than ourselves.'

Not only do these accessories fit right into the Halloween season and whimsigoth aesthetic, they make for stunning decor all year round.
