Last year, Katie Holmes stepped out in New York City to hail a taxi wearing a Khaite cashmere bra and cardigan set, unknowingly setting the fashion world on fire and instantly creating a cult classic top.
A year later, the trend has held on strong, making its way into dozens of celebrities' wardrobes, including none other than that of Hailey Bieber's.
On Wednesday, the model stepped out in Los Angeles wearing a similar style sweater bra by Jacquemus. Like Holmes, Bieber opted for a cardigan and blue jeans to complete the look. It is 2020 so, of course, she wore a face mask.
For practical reasons, the sweater bra has a very specific time period to wear it and the time is now. It's not too hot, not too cold, and it's perfect for some wool boob support. Fortunately, now there are several different ways to get the look including Holmes's exact top here, Bieber's top here, or a crop-top version from Naked Cashmere here.
