We’re calling it the ‘Blue Planet effect’ because this season’s interior looks took a dive deep under the ocean with sea creatures swimming across every surface. From scalloped furniture (we're loving the super scalloped A/W18 Anthropologie x Bethan Grey collection) to fish scale tilesand all things curved, wavy and ocean-inspired, we’ve fallen hook, line and sinker for the under the sea trend.

Livingetc loves Alessi’s Mediterraneo coral-shaped fruit bowl for a tablescape made in marine heaven. Plus, plaster walls with John Derian’s Captain Thomas Browns Shells wallpaper to bring the seabed to life. Time to dust off that snorkel…

1. SCALLOPED SIDEBOARD

Connie's scalloped arches are the perfect way to bring the curved trend home.Showcasing sheer luxe, the Connie’s scalloped frontage (also available in green) pays homage to iconic Deco design. Theatrical and daring, the flashes of brass on this sideboard add the luxe factor.

2. MARINE RUG

Made to make you feel like you're on a beach with your toes in the water, the graphic pattern of the Marin rug reminds us of waves lapping a white sandy beach – or the bright blue scales of tropical parrot fish. Either way, we reckon it'llhelp fend off the winter blues a little longer.

3. FISH SCALE CABINET

The scaled surfaces of Christopher Hall's Triton cabinet are in fact a tribute to goddess Aphrodite, who had a chariot drawn by fishtailed tritons.

4. LOBSTER LOVE

Lobsters mate for life, and we think these vibrant lobster lamps look even better as a pair. Gorgeous for hallways, living rooms or even the home office.

5. LAGHETTO LINEN

The perfect pattern for a fabulously fun cloakroom or kids' room, Osborne & Little's 'Laghetto' (that's Italian for small lake) print features illustratedfish and plant life printed on pure linen.

6. SEA SHELLS

Playful but in a muted palette, this sea shell wallpaper suits practically any room – though we think it'd still be best for cloakrooms or guest bedrooms. Comes in other colours too, including a multicoloured option.

A seaweed-inspired fruit bowl makes an on-trend scarlet centre piece.
