7. Eres

Eres, a Parisian label under the Chanel umbrella, is renowned for its technically advanced swimwear and lingerie. Founded in 1968 by Irène Leroux, the brand revolutionized swimwear by eliminating uncomfortable boning and padding, focusing instead on designs that complement the female form. Their minimalist approach and impeccable fits rival larger names like La Perla, yet Eres remains a best-kept secret among insiders. (elitechoice.org)
