This will be good for hot weather. It is flowy and airy. Perfect with some suede boots for a weekend in Austin or with a leather jacket for a night out in NYC. I am 34 26 35 and bought the S. It is a bit roomy and maybe I could have gone down to XS.
I bought the black and cream in size S. It is very soft and comfy. I would say to take your true size. I am 34 26 35 and it fits like the model. It is cropped, so if you buy larger for extra length you will also get extra width.
