Britney Spears is back on stage and in costume in London this month. While the rest of the outfit looks something like a hot mess, Britney does has some cute ruffled bottoms on. Those same ruffled panties are available in the Three Muses boutique and are on sale for $9.99. They come in Black, White, Pink, red and Baby Blue. There are also black and white ones with attached hot pink garters.
