The early goths (early 1980's) looked similar to the punk scene, except that the predominant colours were black for hair & clothing (with the occasional outburst of white, red or purple) and silver for jewellery. They also tended to spout a lot of fishnet and had a distinctive style of makeup, with very white faces and lots of black eyeliner. Hair was usually dyed black, crimped and backcombed.
At first the hair was usually fairly short for men, but by the mid-to-late eighties long black hair became fashionable and it's now more usual to see hair long & down. Makeup remains an integral part of the look, but clothing has diversified so that some now wear clothes influenced by 18th or early 19th century styles whilst others wear PVC,velvet, leather & fishnet. And some of them wear both, though not usually at the same time. Black and white remain the predominant colours, with red or purple still making an appearance. Distinctive fabrics tend to be silk, crushed velvet, leather & PVC. Overall, the looks tend to be so diversified these days that its hard to pick one "gothic" style
