In Season 4, Steve Harrington sports his signature thick, tousled hair, still voluminous but more laid-back. His face is more chiseled, with a defined jawline and expressive brown eyes showing wear from past battles. He has an athletic, slim build with broad shoulders and toned arms, reflecting his active lifestyle. Steve dresses in casual, retro-style shirts and jeans, paired with sneakers, giving him a rugged yet effortlessly cool look that matches his maturing character.
