Sofia Richie stepped out with her brother Miles on Friday, in Los Angeles, for a birthday lunch ahead of her 21st birthday on Saturday

Sofia worked a white tank top with a grey jersey skirt, completing her look with Adidas' cult FYW S-97 trainers.

Looking casual, the model paired a grey knit mini skirt with a white cropped tank. Sofia's blonde locks flowed in the breeze as she went retro in neon green and grey sneakers, with above the ankle white socks.  .
