Getting it together

For the last few weeks I just been researching so that I can become an expert at my topic which is "How does fashion from the past decades in influence style and trends today?" and trying to find out what my end result it going to be. I keep on asking myself am I doing a fashion show, if so is it going to be a big one or a little one, should I just put a few piece of vintage clothing on and take a picture of it and tell how every piece of clothing is related to a decade from the past. Now I'm doing a pre-writing for my proposal.
