Katy Perry never ceases to amaze her fans, even after her breakup with Russell Brand. Her fashion choices are always unique and stylish, as seen in London where she performed and stunned onlookers in a gorgeous black dress paired with knee-high boots. The outfit highlighted her figure, and the laces on the boots matched perfectly with her bright blue hair. Despite being 27-years-old, Katy was eager to engage with her fans and happily posed for several photographs with them. For an extra touch of glamour, she layered a stunning grey sweater over her already-magnificent ensemble.
