After all, we’re heading into prom season, and Hollywood couples like Jason Momoa and girlfriend Adria Arjona are going to held up as style icons when it comes to picking what to wear. Well if their get-up from an event celebrating A Minecraft Movie’s debut is any indication,

Momoa wore a purple velvet suit with a wide-lapeled jacket and matching trousers, paired with a white shirt for contrast. He left his hair down, sticking to his laid-back style—fitting for his role as Garrett 'The Garbage Man' Garrison.
