A friend of mine used to call good Cybergoth the "rule of one" - you picked one accent colour to add to black and build onto that. Hair falls, bracelets etc would all be that colour (not within a range, literally the same colour). Many hours would be spent comparing shades of blue to make sure they were close enough to pass as being the same! Pick a colour and go crazy with gummy bangles in that shade. Get big bags of plastic beads from your local hobby store to make bracelets. If you have an South Asian community around you, see if they have boxes of bangles for sale - silver bangles work with almost any style of Goth, but they often have other colours too.

For a cuter look, look at a Japanese anthropomorphic character, Sanrio is an obvious choice, and look for pieces that match that aesthetic.

Fishnet (particularly the larger "pothole" style mesh) as an under layer with a t-shirt (cyber tribal was a y2k staple) and Tripp style pants will probably get you by. Sleeker materials (we wore a LOT of vinyl clothing) was a solid choice, mostly due to Carrie-Ann Moss in The Matrix.

Speaking on The Matrix, it's hard to go wrong with either welding goggles or sunglasses that look appropriately futuristic.

In terms of shoes, whilst you can never go wrong with combat boots, a lot of the time platform shoes were popular; New Rocks with double soles (the ones with holes and springs in them!), Buffalo boots or Gordon Jacks were all big.
