While trench coats, oversized hats, checked fabrics and cowboy boots were undoubtedly some of the year's biggest trends, the jewellery world was igniting (or, rather, reigniting) cult styles of its own.
Asymmetrical pearl earrings and diamanté hair slides may have been a recurring theme, it was the shell-embellished pieces that dominated the accessories landscape in 2018.

Shell bracelets, shell necklaces, shell earrings, shell anklets, shell-embellished sandals... heck we'd wear jumpers adorned with the chic little crustaceans if only someone would make one for us. We only draw the line at lingerie (but perhaps a bikini would be cute?).
Shell-mania hit fever pitch this summer having first been seen at the runway at Prada back in February 2017 for the autumn/winter '18 collection.

As is the case with most nostalgic trends, Instagram was awash with the pieces this year decorating the necks/arms/wrists of some of the world's chicest influencers.
The trick to pulling off the trend right now - as opposed to the mid-nineties - is to avoid all things too plastic-y. Instead, channel the look via chic gold-toned pieces with cream or silver accents in delicate designs.
Brands particularly excelling in the shell-accessory arena include the likes of Isabel Marant, Tohum, Ellery and Aurelie Bidermann.
