I find it to be true to size, slightly tighter at the hips but not the waist. I would say tts but size up if you want to wear it lower on your hips. I am in the medium of the tank and the sweater. It’s not a set that’s sold together, but they do go together. I promise. I would say TTS but fitted on the tank and TTS on the button cardigan top thing.
