Goodwill has some cool stuff that has to do with that, Hot Topic is also a place you can look at, it has a lot of stuff with that look, you can try Spencers, I'm not really sure about that, but it won't hurt to try and see.
Amazon.com has some fishnet shirts that you may like - http://funadvice.com/r/14slk1vdpt3
They also have thigh high stockings, if that is what you are looking for - http://funadvice.com/r/bguo8jqagkn
Try thrift shops, online shops like polyvore.com or spencer.com might have them too.
or your nearest stores close to your house or malls
