Cotton clothing if possible nothing with nylon in. Cropped trousers and a vest top indoors. A long flowing skirt and top when going out and comfy sandals.
90% of the time light, flowy, linen or cotton midi skirts or dresses. Nothing tight, nothing heavy. T-shirt and sandals and that's it (well, and undies).
What are you wearing? I have bought a lovely jersey dress from white stuff called Leah. For me it ticks all the boxes, lightweight, pockets, decent length, sleeves!
