The first thing to know about this tank is that it’s knit from Italian virgin wool: a natural, breathable, temperature-regulating fiber that’s unexpectedly brilliant for the spring months. The second is that it’s slim-fit and ultrafeminine, designed with a deep V-neck and a scooped open back. Ribbing that extends from bust to hem creates a subtle corset-like effect—and if you want to define the waist even further, there’s a skinny tie you can cinch to your liking. Which brings us to point number four: If you like this design, you should also check out the Isa Dress.
