1.
Katy started out her musical journey with very silky pants and very pointy shoes.
2.
Eventually, with the help of this massive faux flower, she transitioned into a young hopeful musician.
3.
You can see the beginning stages of her retro-inspired aesthetic come to life around 2006.
4.
Although after a year, she steered away from the "Joan Holloway" look.
5.
The lady's been experimenting with different fabrics and patterns since day one. Exhibit A: Fruit dress.
6.
Exhibit B: Satin '80s dress.
7.
She looked that girl who lives next door, but doesn't really, in this casual dress with nonchalant hair.
8.
After "I Kissed a Girl" debuted, her getups were more and more vibrant. A modern-day Little Mermaid, if you will.
9.
Her makeup even matched her clothes.
10.
In 2009, she got a bob and updated those silk pants.
11.
Katy looked like a beautiful birthday cake in this lovely dress. Not to mention her makeup looked fantastic.
12.
Eventually, she spiced things up with crop tops and sequins.
13.
She looked like a regular California gal in this colorful jumpsuit.
14.
Ultimately, her signature look was revealed during the summer. Minnie Mouse-chic, you could call it.
15.
Waking up in Vegas, perhaps? This showgirl-inspired outfit made an appearance in 2009.
16.
Fast-forward a wee bit, her makeup is less theatrical and her formal attire is more modest-ish.
17.
She must've been inspired by the '60s with her floral gown and straight-across bangs.
18.
The popstar persona is in full effect at the Kids Choice Awards in 2010.
19.
More than a year later, she's moved onto her high-fashion wig phase.
20.
Shortly after, she tries out the "fancy ice skater".
21.
Eventually, she's back to black looking like a classic Hollywood starlet in this beautiful gold, off-the-shoulder dress.
22.
Her wardrobe from 2011 is gorgeous. Period.
23.
Maybe she was in the mood to mix things up with new hair at the Smurf's premiere?
24.
Certainly so at the AMA's.
25.
One of my personal favorites was this crazy outfit paired with her memorable blue bob.
27.
Who didn't love her goth-inspired phase?
28.
Fall 2012, Katy looked like an actual movie star.
29.
Then the Queen of Pop come Spring!
30.
This effortless stage was one of her personal best.
31.
She's still the same Katy: Dressing for herself and no one else!
32.
Finally, we'll end on this.
