One of the things I feel is trendy now is movement. There must be a balance between being frumpy and showing off curves. In my outfit, I balanced my incredulously large pants with a simple tight tank top. Another way to manage the balance is with sheer. A light colored loose flowing sheer shows off whatever you are wearing in a contrasting color.
Good luck with your future twirling clothes!
