NWT Serena & Lily Size: California King Color: Oyster Bay (Sky/Coastal Blue) We love a good beachy stripe. Here, a little flourish along the trim adds a bit of texture and playfulness, making the look more dynamic. For a super-soft touch, we chose a specially washed, yarn-dyed cotton sateen – the drape is so inviting, and we love the matte finish. To get the details just right, we travelled to Portugal (a country that knows a thing or two about beautiful textiles). Eco-friendly cotton makes this free of harmful chemicals.
