When you are on stage, you are often between 30 and 100 feet from your audience. So thinking about your costuming and how it is going to interact with the elements of the stage is important.
Stages often have a black curtain backdrop. If your venue has a dark backdrop and you are in a dark costume -- you might just disappear! If you add dim lighting to the mix, it’s possible that the only bits of you that are going to be seen are the body parts that aren’t covered – so you could literally just be a floating head and belly if you aren’t careful!
I always recommend going big and bold with color on stage unless you have a very good reason for using black or a dark color. If you are going to use black or a darker color, then think about how you can embellish the costume to make it shiny or bright – some element of additional POP that can be seen from the audience.
If going to a large festival, check out the previous years photos/video to find out what has been used in the past and what the lighting looks like as well. You can always ask too. If local, just ask your promoter or call and ask at the theater.
This little bit of planning can really make a huge difference in your visual presentation!
