Dramatic shoulder ruffles are something of a Johanna Ortiz signature, and we love the way they frame the St. Kitts swimsuit, part of the exclusive capsule collection with mytheresa.com. Showcasing that one-piece designs can be just as flattering as their bikini sisters, this style comes with cut-out detailing at the waist that highlights hourglass shaping. The ruffled straps finish at the back with a tied bow, while the rich ivory hue will allow even the fairest of skin tones to glow. For poolside jaunts, team yours with a pair of colourful slides and a woven shoulder bag.
