Hailey! Jane! Sabrina! The Simple Top It Girls Have Been Wearing Since the '60s
It's just as popular in 2026.
Every single one of my fashion editor friends raves about the Cou Cou Intimates Rina top. I'll be honest, I didn't originally get the hype. How could a 3/4 sleeve top be so life changing? Then I tried it for myself and immediately understood the appeal.
It is just the perfect top. It's easy to wear, looks good with everything and has just enough subtle details, like the scalloped edges, to make it distinct. I now own one in both baby pink and black and have worn them on repeat since they've been added to my closet. They're just that good.
Hailey Bieber and Sabrina Carpenter agree. The two style icons also own the top and have worn it on multiple occasions. If you don't believe the top's powers, just step outside in downtown New York and I guarantee you'll see a handful of Rina tops within an hour.
The top silhouette isn't anything new, it's been big since the '60s and was a piece often worn by Jane Birkin. Clearly, it still feels as effortless in 2026 and is a must for anyone.
