Summarize:

However, you can also grab an oversized red blazer and cut out pieces of blue or black felt for the cuffs. Use black felt for the oversized collar. For the gold clasps along Britney's chest, you can either embroider on a design or make one with thick gold rope and append it with glue. Britney has black fishnets underneath, but you could also wear nude tights. Ones with matching gold clasps don't hurt either.
Britney sported this look in her 2009 tours for her album Circus. The most realistic way to pull this off would be to purchase the ringmaster jacket from a costume store like Diddams or Spirit Halloween. Wear black spandex shorts or swimsuit bottoms. It wouldn't be true Britney style unless you sported a pair of large, black leather boots. Accessorize with a black top hat; it's a traditional part of any ringmaster's repertoire. Use eyeliner to draw on a curly mustache, or purchase a fake one from a costume store to complete your look.
