New and Need Help!

Hello! My name is Nadia Wolfbane and I am very new to this style. I've read books and such but can't seem to get my ideas to come to life. Halloween is rapidly approaching and my daughter suggested finally doing a steampunk costume. I do not have one however and need help on how to make these pieces I already have work. I hope y'all can help me! I also hope this link works as this is not letting me add a photo from my phone...??
