The younger Hadid pulled her blonde hair back into a neat bun and she wore sepia-tinted aviators.

She was adorned in jewelry that included layered gold necklaces and small earrings.

The designer and mother-of-one carried a small black leather handbag as she headed to a waiting car.

Despite the sad occasion, the beauty smiled at fans and gestured with a thumbs-up.

Yolanda wore black leather stiletto boots with a pointed toe and she also wore aviator-style spectacles.

Her frosty blonde locks were arranged in a sleek, spiky top knot bun and she wore a light face of makeup.

The former agency president passed away at the end of October following an unspecified, short illness.

He was 60-years-old and had stepped down from his role at IMG in March of this year.
