He's saying aloha to a new style!

Justin Bieber has been putting on quite a show in a variety of Hawaiian shirts these past couple of weeks, so we thought we'd break down his fashion formula for you and ID some of the pieces so that you, too, can dress like The Biebs!

JB first rocked the $153 Gitman Vintage Blue Aloha Camp Shirt at Post Malone's Hollywood concert back in June, before he re-wore it to church with Hailey Baldwin on August 27th. Both times, he paired it with black Vans sneakers, which made it a little less dad-like and a little more chic.

Then yesterday, he wore a $1600 Gucci one from their womenswear line on an outing to the doctor with Hails, along with $487 Selvedge Denim Vintage Shorts and Adidas shower slides.

He must have wanted to be more toned down for nighttime, though, because he changed into a $451 Amiri cream and black leaf print shirt to catch a screening of Crazy Rich Asians in LA with his lady love.

Get this guy to a luau, stat!
