The top: This is a very lightweight knit top; it’s comfortable and cool for summer. It does run generously – I am in the large and it’s probably too big but I like it so I kept it. Stay TTS or even go down a size if you are in between. I’ve washed this one (hung to dry) and it washed out perfectly, not shrinkage or fading. The shorts: I'm in the large, size up for a looser fit1 Non-sheer and comes in lots of colors!
