You're asking us to choose things that will help you, make you, "more you", which isn't actually you, but a set you associate with.

If you want ideas for "Romantigoth", type in "Victorian Clothing" and go through the sites it lists. This will give you some idea of what you should be looking for. The best part is that you can weed out what you want to buy before you buy it, so you know the idea will look somewhat decent. Here's a relatively decent source:
