Okay, so this Sabino Knit Polo Shirt from Sergio Tacchini is a total winner if you're looking for something smart but still super chill. It's proper 100% cotton knit, so it feels really soft and breathable on, which is key whether he's out and about or just lounging. It's got that classic polo look with short sleeves and neat ribbed details on the collar, cuffs, and hem, which just makes it feel a bit more put-together than a standard tee. The deep maritime navy colour is really versatile too, so it's easy to pair with most things. This one works for pretty much any vibe – from a casual weekend brunch to a slightly dressier date night. The regular fit is comfortable and not too fussy, making it a reliable pick for any season.
