Heavy metal fashion refers to the fashion, clothing habits, and general appearance of heavy metal fans. It typically consists of black clothes, t-shirts (often sporting a logo of a Heavy Metal band, a Heavy Metal album cover, or images of the band itself), spiked or studded belts, jeans (sometimes ripped, and almost always blue or black denim) or leather trousers. Clothes worn over T-shirts are typically leather biker jackets or denim jackets. Popular accessories include: spikes, chains, tattoos, body jewellery (often silver), sometimes black eyeliner (black nail polish is also not uncommon), and long, ragged hair. The hair in heavy metal is important, and almost all metal bands have some long-haired members. Footwear is often combat boots, "biker boots", or construction boots, rather than the more stylised footwear of Goths. Traditional heavy metal fashion has some crossovers with Goth and Grunge clothing, particularly in colours, and the amount of body piercing.

Heavy metal fashion has seen a recent resurgence in the UK (and to some extent in the US). Mainstream 'pop' fashion retailers have picked up what is accurately labelled as a cross between heavy metal fashion and skater fashion and are successfully marketing it under the labels 'goth' or 'rock' fashion. This typically consists of t-shirts and hooded sweatshirts with heavy metal, nu-metal, or punk logos, paired with baggy 'skater' jeans, chains, and dark colours. This is largely the result of the increasing popularity of nu-metal and skateboarding in the UK and the USA.
