1. Comfy & Casual

Not only do Bieber and Richie regularly sport edgy black hoodies, but they both keep their hoods pulled up and over their heads. The "Sorry" singer recently paired his sweatshirt with a baseball cap and khakis, while Richie dressed hers up with strappy heels and distressed skinny jeans.

2. Signature Accessory

When in doubt, throw on a bandana! The two love a good kerchief, and we can't blame them.

3. Band Tees & Distressed Denim Jeans

Looks like the duo share a passion for classic rock music, too! Bieber donned a colorful Nirvana T-shirt with ripped jeans to the 2015 American Music Awards, while Lionel Richie's daughter was photographed wearing a Def Leppard baseball tee in Los Angeles.

The blonde model paired her low-rise camouflage pants with a cropped jacket and black hat for an impromptu Instagram photo shoot. Her beau, also clad in a black hat, opted for a camo jacket over a black hoodie while performing onstage during his Purpose World Tour.

5. Babes in Braids

Not everyone can pull off cornrows, but these two seem to do it well! Richie had some extra fun with the trendy 'do, incorporating pink extensions into her braided tresses.

6. Wild Style

Bieber rocked the stage at the 58th Annual GRAMMY Awards in a bright cheetah print jacket, which perfectly complements the chic one Richie modeled during one of her fashion photo shoots.

7. Homage to Hip-Hop

He loves Tupac, she loves Snoop Dogg -- their nearly identical graphic T-shirts seemingly prove their appreciation for rap most likely played a role in their coupling.

8. Vibrant Outerwear

But seriously, do these two share a closet? Bieber and Richie both turned heads in their colorful bomber jackets.

9. All-Black With White Kicks

When 75% of your wardrobe consists of black apparel, sometimes you just have to rock an all-black ensemble. Bieber and Richie did just that, styling their dark-hued outfits with white sneakers.

10. Hot Headgear

You can never go wrong with a beanie, and it looks likes Bieber and Richie have quite the collection! The two are frequently photographed wearing the accessory in various shades.

11. Motocross Muse

Richie turned 18 on Aug. 24, donning an ultra-sporty look for her birthday bash held one night earlier at Koi restaurant in Los Angeles. She wore a pair of motocross-inspired pants with a simple black tank top. Perhaps she took a style cue from Bieber's sexy dirt bike get-up?

12. Rockin' the Basics

An oversized gray top over a pair of black skinnies is a fashion favorite for this cute pair. Bieber styled his outfit with black-and-white kicks, while Richie went with black stilettos.

Blond hair. Brown eyes. A sophisticated white blazer over a classy shirt. Couples who dress together, stay together, right?
