Katy Perry Werks It in Matchy-Matchy Viktor & Rolf

Just when we were about to be over Katy Perry's cotton candy-blue locks, she goes and pulls off an ensemble like this. If she continues to revolve her style choices about her hair like this, we guess she can keep the 'do for a little longer. Usually the matchy-matchy look can come off looking pedestrian, but KP has just the right amount of spunk to make it work.

When she arrived to the Viktor & Rolf Ready-To-Wear presentation in Paris on Saturday, she stayed true to her style wearing a whimsical cobalt trench with swirly lapel cutouts by the headlining designer along with a coordinated shift dress and aquamarine pumps. We loved the wave-inspired designs of her costume-y ensemble and felt it embodied her quirky personality much more than the Vegas showgirl-like Balmain minidress she sported last week.

Statement-making ensemble aside, we couldn't get over the limited edition Christian Louboutin pill capsule clutch she punched up her look with. We seriously need that bag in our lives!

Sheer is definitely here to stay by the looks of it! Giambattista Valli dressed this model in a textured, sheer maxi dress. We loved the illusionary feel of the frock and can definitely see celebs donning it soon. 

Vampy and sexy seemed to be the theme for the Jean Paul Gaultier fashion presentation with many of his models wearing dark and Gothic-inspired looks accented with sultry thigh-high splits and billowing black capes. 

French fashion house Lanvin fused intriguing three-dimensional aspects into its pieces this fashion week. In a unqiue twist on the LBD, this model wore a black strapless with exploding ruffles wrapping around the bodice. 

The newest collection by Hermes had a futuristic, dystopian vibe with dark, contrasting fabrics used on many of the models.
