Katy Perry looks fantastic in head-to-toe blue

Singer Katy Perry continues to move on up in the world, as she expands her product line to new false eyelashes. She started with nail polish then went to perfume, and is now promoting her Katy Perry Eyelashes by Eylur, according to E! News.

The Firework crooner attended a meet 'n' greet to promote the eyelashes with 100 lucky fans, and she was decked out in a blue outfit from head-to-toe - including her aqua-dyed hair. Perry wore a two-toned blue dress with matching wedges. The brightly-colored star chose the same hue with her jewelry as well.

Not only did she wear a complete blue ensemble, but she also showed up in a vintage aqua-blue convertible, the news source reports.

The singer has recently been going through a very public separation with actor Russell Brand, so it comes as no surprise that she has retired her wedding band and engagement ring. However, she still wore some fantastic jewelry including at Solange Azagury-Partridge ring, blue bracelets and another blue ring, according to People Magazine.
