Purchase some armbands or necklaces. Try to get ones with skulls or Gothic bands (Bauhaus, The Cure, etc). Also, get some badges and chains that dangle off your clothes. Boys can accessorize adequately such as aiming for a decent belt, black leather with metal studs, dark imagery, and a cool buckle. Necklaces can be spiked chokers or they can be long and light like silver roses or cobwebs. Girls can opt out for ribbons around the neck in a choker style. Mix up many necklaces with a choker. It looks classic. Boys can opt for chains hooked to their pants. Girls can finish off the look by some beautifully dark, gothic nail art. Handkerchiefs are a basic element for a gothic look. You can embroider on one to make it your very own. Maybe a cobweb on it, maybe a quote etc. Make it your own. Boys can accessorize using hats and girls can attach some feathers in your hair or net around a little edgy bun. If you're more of a rocker Goth then go for a large number of darkly colored same-looking bracelets. It'll rock your look! Keep in mind that long socks can make an outfit stand out brilliantly. Perhaps wear a mini, fishnets, and black one with patterned socks over the fishnet. Take a number of rings that match and wear them around on random fingers to add the gothic glamour to your outfit and personality. For girls anklets can a add a little spice to their look. This looks pretty cool. Both boys and girls can go for dark colored hair dyes. Black is the basic one but you can definitely go ahead with other dark colors too such as burgundy. The more sensual styles, such as the romantic got hand Cabaret Goth, usually favor long and dark. More hardcore or punk fallen styles, such as Death rockers and Cyber Goths, usually have brighter sort of hair.
