Pants: 100% SOFT linen. they run roomy. Safe to go with smaller size. I went with large but could easily do medium. Drawstring waist allows for custom fit / snugness Top: part of an amazon set- it isnt cotton but surprisingly feels like cotton ( i wore all summer) BUT i want to invest in the 100% cotton set i linked from o.p.t .
