Go ah
ead! Just wear whatever you want. This is a free world. Don't be afraid of what people might and will think. You can't avoid that, though. People are also free to think whatever they want to think. AND THEY WILL ALWAYS HAVE SOMETHING TO SAY. But remember that this is who you are, and this is how you express yourself.
Remember when people used to say that the 80s fashion is so ugly and unfashionable, but look at the trends emerging right now - it's directly influenced by 80s fashion!
If you are afraid of being harshly judged, start slowly and dress like the style you have in mind in a "tame" and mild way. Gradually build up as your confidence and sense of identity grows.
