It’s not always easy to pull on the same fits you see A-list celebrities from Ryan Gosling and Michael B. Jordan to Dwayne Johnson and Tom Holland wearing when they're out looking like leading men. The red carpet can be a pretty wild place these days. But there's definitely one item that's become something of a hero piece (and you don't have to play a superhero to wear it). We're talking about the knit shirt.

Over the past few seasons, it's gone from a rogue, vintage-inspired piece that early adopters mixed into their warm weather wardrobes to a bonafide menswear staple. Why? Well, it's seriously cool. These soft styles, knit from cotton, linen or lightweight wool yarn, give you an immediate rich-looking, throwback vibe. Like there's a Rat Pack swagger knitted into each and every one. Decidedly more dressy than the standard button-downs and polos, these shirts have a luxe, worldly air to them and can be worn with everything from chinos and shorts to a pair of equally right-now pleated pants.

What's more, they look good on just about anyone and every body type. Which is another reason why they've become a go-to for celebrities of all shapes and sizes. Put another way: The knit polo has range! Plus, if you don't want to wear a tie with your lightweight suit, these look particularly chill under a jacket. In short, they're as easy to pull on as your everyday T-shirt, but with their retro collars and soothing textures, they make for a one-step move to nail sophisticated warm weather style.
