Sky Pirate costume- skirt and skirt wrap would be an easy make. So would the belt. Have pattern for the different corsets. Or forget costume: just wear this when you don't want anyone to mess with you. Like an audition. Or the DMV.
Choosing the steampunk theme for a wedding is rather daring in itself, so choosing an outfit don’t hesitate to wear almost crazy things! I think that a steampunk bridesmaid’ outfit is something really creative.
