There is nothing like the art of complemented couple dressing when it comes to Hailey and Justin Bieber.

Hailey and Alaia were spotted out in LA yesterday while headed to Alaia's daughter's birthday party. 

Casual ensembles with loose-fitting, summery pants complemented the couple's casual look perfectly. 

White sneakers and taupe cargo pants complete the look. She wore beige sunglasses and half-up hair. 

He wore a Kanye West merch tee under his long-sleeve shirt. A baseball cap and sunglasses completed the look. 

Justin posed for a picture without a shirt while Hailey played with the toddler during the couple's birthday visit. 

Hailey captioned the picture with "there was a little princess who had a birthday party today.". 

The singer and model have been inseparable since their back-to-back health scares earlier this year. 

Hailey opened up about how their marriage has evolved over the past four years in the September 2022 cover story. 

Life changes constantly. We've had a stressful six months. It's all crap, right? "For better or worse!"
