D3 Clothing became an idea in December of 2017 when trying to find a way to commemorate for losing a classmate to suicide.
D3 Clothing was launched in January 2018, with four styles of hoodies and four hats.
The Fall Drop of 2018 was one of D3's biggest successes. Some of its current styles were released focusing on the words "Dedicated" and "live life" to focus on both one of the brand's main components and the mission behind the company.
The release of the D3 "Box Logo Crew" was to focus on the three brand words in a different style.
The first "D3 Designer", Jenna Penticoff, created Full Bloom which was of D3's fastest sellout.
D3 attended its first event, RiseFest, hosted by Rob Rozenboom in Sheldon Iowa. Here, Tony Harris, D3's founder, was invited as a seminar speaker to speak about the company's origins about D3's efforts towards suicide prevention.
