The simplistic look of white and black tie combined with the long vinyl trenchcoat and platformed boots are amazing on their own. Collars and cuffs can all be bought for around 10 dollars a piece. A good rule about buying a collar as a male is to get a thicker width as to not make it look to necklace-y. Look at BDSM oriented leather stores and see what fits your personal style. Bondage and electrical tape are also nice accesories.
Electrical tape tends to be too small a width, but bondage tape is nice and wide.
Some other added benifits to bondage tape is it is reusable and is made not to stick to hairs. Wrap some around your arms as bands. You can also go to an electrical outlet store and buy circuit boards or diagrams and add them to your outfit with bondage tape. This is a definate eyecatcher so be prepared to stand out. Gallery Serpentine also makes a line of Dead Tech items like male waist cinchers and t-shirts with circuit diagrams printed on them.
