Scarlett Johansson's take on the Knit Shirt Trend is practical and polished, with her recent Instagram post showing a sleeveless knit sweater. The lightweight top offers warmth without feeling heavy and makes layering easier. Similar styles can be found at Amazon starting at $15. Other notable examples include a wool-blend tank with a subtle V-neckline and sleeeless design, which fits seamlessly into a capsule wardrobe. Meanwhile, celebrities like Hilary Duff and Kate Hudson have also worn the trend.
