The material on this is PERFECT. So soft and comfy. Perfect to pair with some cute jean shorts or to work out in. Went with my normal small and could have went a little bit smaller - but loose and comfy and easy to knot.
Rated 2 on a scale of minus 2 to 2, where minus 2 is Runs Small, 0 is True to Size and 2 is Runs Large
