Soft and springy basic waffle knit sleeveless top made of Italian viscose. Please note there are some minor flaws: a very light stain at the top of the back that did not come out after 2 washes (though it did lighten significantly, so maybe it will come out eventually or with better laundering skills), and a tiny spot of damage on one corner of the waffle knit. Measures 16" pit to pit laid flat. Pretty stretchy
