One of the most popular beach towns in Mallorca is Deià, a quaint area that’s known for the Belmond La Residencia hotel. An absolute must-visit, if even just for lunch. The terrace has the most postcard-perfect views of the Tramuntana mountains. I wore a breezy, scallop-detail dress from Paper London. It’s the details that make the beachy throw-on look so expensive—the contrast embroidery, the continued scallop feature on the shoulder straps and, best of all, opaque cotton, which really should be the standard but is remarkably difficult to find.
