Although he was born in 2000 to Nigerian parents, Abolaji Oshun grew up in East London, specifically in Newham and Hackney. For him, modeling started growing in childhood, only to be realized by model agencies in his hometown after his friends convinced him that he could model and cheered him up to try.

After doing well in the trials, Abolaji O. was scouted in Westfield Stratford City in 2015 by an agent, marking the start of a long journey into modeling while still a student. When he signed up with modeling agencies, Abolaji opened up for professional engagements that resulted into great deals. In 2020, he walked for Balenciaga in the Balenciaga F/W 20 Show, advertised Louis Vuitton, and appeared in i-D X AMI and AMI-Fall 2020 editorials.

In 2021, Abolaji Oshun was featured in Hero Magazine, Man About Town, Mr. Porter, and Wallpaper Magazine editorials. Besides, he did a polaroid dubbed Supa 2021 Polaroids in January. In 2022, he did an advertisement for Polo Sport S/S 22, and much might be in his pipeline.

Interestingly, Abolaji Oshun has been juggling modeling and school, despite challenges like the COVID-19 outbreak that completely interfered with his tight schedule.
