Katy Perry looked beautiful while posing on the pink carpet for the premiere of her documentary/movie "Katy Perry: Part of Me 3D" which took place at the Grauman’s Chinese Theatre last week in Hollywood.

The singer wore a bright red Dolce & Gabbana strapless velvet dress with a full skirt and sweetheart neckline paired with matching Dolce & Gabbana pumps and  Tacori jewels.

For the beauty look, Katy went for some retro glamour with voluminous curls, dark eye make-up and a deep red lip colour.

In true Katy P. style, she carried a cute Judith Leiber crystal "cake slice" clutch with a cherry on top!

She somehow made the look ulta-glamourous, even though purple hair and a head-to-toe red outfit wouldn't usually be on the best-dressed list!

For her performance, Katy swapped her ladylike dress for a more fun, movie-themed ensemble. 

Her eye-catching dress featured a film-reel bra and a red and white striped skirt with a popcorn accented hemline.
