I'm All About Natural Fabrics for Summer—32 Easy Pieces Already in My Cart

      I frequently shop, which allows me to use various methods to find exactly what I'm looking for, such as filtering by specific materials. During warm weather, this often means opting for 100% cotton. I have a particular fondness for lightweight cotton dresses (like those in the sleep dress trend) or simple skirts from brands like Cou Cou, Doen, Donni, Enza Costa, Flore Flore, Leset, Rue Sophie, St. Agni, and others. Another natural fiber I prefer this season is silk; one of my favorite brands for it is the Australian label Silk Laundry. A silk slip dress is always an effortless choice with ballet flats or kitten heels, while still appearing polished. I also wear cashmere throughout the year—even in warmer temperatures. Since I tend to feel cold, I always have a lightweight cashmere sweater handy for when the air conditioning is on or it gets cooler in the evenings. J.Crew even offers an entire section called The Cashmere Shop that features numerous lightweight selections. Below, you can find options in 100% cotton, silk, and cashmere for summer 2026.
