I loved this sweater – I ended up buying both of these pieces. This is a 100% cotton sweater and it runs very oversized. This is the small and it’s still quite big! I would have probably gone for a medium but there was just a small left. So hear me when I say this runs very big! Love these pants – they have more of a wider leg and a drawstring waist. They are not as long on me as the model, perhaps had I gone with a large they would have been? But otherwise they fit TTS. I’m in the medium.
