Despite being made of a minimal amount of fabric, investing in swimwear can sometimes feel like one of the most difficult decisions one can make during summer. However, as the chicest dressers galavanting around balmy European destinations like Sicily, Ibiza and Marseille can attest, opting for one of these key bikini colour trends will ensure you always look polished, even if your plans involve languid dips in turquoise waters and soaking up every ounce of Vitamin D imaginable.

Speaking to Maria Sinkovskiy, the founder and designer of French swimwear brand Du Ciel, she explains that “swimwear is something people wait for”, proving how entrenched the bikini you invest in is to your overall summer mood. “You wear it on holidays, long summer days, special trips and it becomes part of your memories,” she notes before adding that “swimwear awakens emotions.” “It smells and tastes of vacation, which is something you remember forever.”

Though you may not recall the name of that particular restaurant you went to on the final night of your trip or the beach club you spent hours at during a blistering afternoon, you’ll always remember the swimsuit you wore to see it through, making the piece you choose far more sentimental than you’d expect.

“Swimwear has always felt incredibly personal to us because it reflects the way we actually live and dress,” echo Sami Lorking-Tanner and Evangeline Titilas, the co-founders of resortwear brand With Jéan. “For us, swimwear isn’t separate from fashion. We love designing bikinis that can be styled beyond the beach, making them feel like true wardrobe pieces rather than something you only wear on holiday,” they add.
