In the third season of The Big Bang Theory, we were introduced to Sheldon's potential love interest Amy Farrah Fowler. As a neurobiologist, Amy's idiosyncrasies matched many of Sheldon's, making her a fantastic match for this rare specimen that is Sheldon Cooper.

After spending years together as friends and lovers (without intimate love), Amy broke up with Sheldon at the end of season eight after not getting anything in return from their relationship. The two tried to remain friends but by the ninth season, these two were back together and ready for the next step.

Out of all of our favorites on The Big Bang Theory, it was extra special to watch Amy grow from a shy neurobiologist with no friends to a blooming, self-assured Nobel Prize recipient with a husband and a core friend group. From season three to season 12, let's take a look at some of her best (and worst) fashionable moments.

WORST: TOO MANY PATTERNS AND LAYERS

Amy and Sheldon have a serious conversation

Thanks to Howard and Raj, we first meet Amy after the duo looks for a mate for Sheldon on a dating app. Seeing as Amy was as robotic and dry as Sheldon, they knew she'd be his perfect mate.

Over time, Amy became less robotic and more human — even wanting to be best friends with "popular girl" Penny. Her style also progressed. She still wore vests and sweaters but they had more designs and colors than the former stripes on stripes on stripes look.

BEST: HER NOBEL PRIZE

Amy and Sheldon accept their Nobel Prize in TBBT finale

There was no moment greater than seeing Amy shine like a diamond at the Nobel Prize ceremony. We've seen her go through so much in her career and personal life with Sheldon that this fictional ceremony made many emotional. We watched Amy grow from an ugly duckling (so to speak) to a glorious swan in her own right. She even has feathers on her shoulder to highlight that fact.

Deep down, every fan of Amy is obsessed with the fact that she glistens when she puts on a tiara. If she wanted to wear a tiara at Penny and Bernadette's weddings, why wouldn't she do the same for her Nobel?

WORST: HER DISNEYLAND OUTFIT

In the 10th season, Amy and Sheldon went to The Wizarding World of Harry Potter over at Universal Studios in Disneyland. As you'll see in the point below, Amy went to The Wizarding World of Harry Potter without Sheldon, a fact that greatly upset him.

This could only mean that she and Sheldon had to go back to Universal just so Sheldon wouldn't feel left out. When they returned from their long day, Amy was decked out in Hufflepuff gear while Sheldon was in a Griffindor robe. And while there's nothing wrong with Amy being in Hufflepuff, the sweatshirt mixed with her hat is overkill.

BEST: DRESSING UP IN A HARRY POTTER ROBE

This Harry Potter-themed ensemble, on the other hand, is very much accepted. Seeing Amy try to spice up her bedroom life with Sheldon by dressing in Hogwarts garb is something no one saw coming but made all the sense in the world.

Amy is totally a Hufflepuff and seeing Sheldon light up at the sight of her dressed in the Wizarding school's robe was everything he didn't know he wanted. It also gave us a peep at their bedroom life which was saucier than we expected!

WORST: HER SICK GIRL NIGHTGOWN

Amy is a beautiful, young woman who doesn't always act it. Granted, she seemed to have more energy than Penny on most days but her clothing choices didn't always match that.

When we see Amy sick or getting ready for bed, she's typically in a nightgown that goes down to her feet. It's great that she's comfortable but her nightgowns age her. She's a spry, young woman who, for the better part of the show, tried to entice Sheldon to sleep with her. A nightgown like the one above doesn't do much for our favorite neurobiologist.

BEST: HER NAUGHTY SCHOOL GIRL MOMENT

In "The Anything Can Happen Recurrence," we see Sheldon and Penny going through a rut with work. Penny is sick of playing a woman who turns into an ape and Sheldon has grown tired of string theory.

Amy and Bernadette decided to take a break from Penny and Sheldon by going out to dinner; however, they were caught by them. To make up for behaving poorly, Amy dressed up as a Catholic school girl to get Sheldon's blood flowing. Sadly, the only thing that it did was confuse him. Nevertheless, Amy looked amazing! (She should also wear ties more often!)

WORST: CORDUROY ON CORDUROY

Amy isn't shy to wear layers. She typically wears an undershirt, a vest, and a sweater on any given day. But all those layers don't do much for her. Here, we see Amy in a corduroy skirt and jacket!

If that wasn't too much as it is, she's also wearing thick grey stockings, a yellow vest, and two undershirts! As a resident of California, isn't she constantly sweating?

BEST: PROM

In the eighth season, the gang decides to do a prom do-over. Everyone gets decked out and transforms Sheldon and Leonard's rooftop to an outdoor prom extravaganza. Everyone looks dapper and beautiful but it was the first time we saw Amy all dressed up.

In a powder blue dress with matching earrings, Amy looked like a princess. To make her beauty shine even brighter, this was the first episode we saw Amy and Sheldon profess their love for one another. It was a beautiful moment for a beautiful woman.

WORST: STRIPES AND FLOWERS

In the episode where Bernadette was picked as a female scientist with brains and beauty, Amy grew jealous and annoyed. Science wasn't about beauty and she didn't understand why the two correlated. If anything, she thought the title was demeaning.

That being said, Amy had more important things to do in the world of neurobiology than worry about the kind of sweater she was going to wear, but this sweater and floral shirt combination was not our favorite.

BEST: WEDDING

While Penny and Bernadette (secretly) made fun of Amy's wedding dress, Amy never felt more beautiful. She loved her swan-like dress and felt even better. She was covered head to toe in white lace and pink ribbon.

Amy also wore a thick lacey vail. When she stood next to Sheldon, the two looked like the ideal cake-topper. Amy looked as stunning as she did because she felt so confident in the gown of her dreams.
