Cardigans & Casual Terrorism

Summary:

When Bellatrix Lestrange lands a date with Hermione Granger, she enlists a deeply reluctant Harry Potter (and an overly enthusiastic Ginny) to take her shopping for Muggle clothes.

Work Text:

The sheer cosmic absurdity of the situation was not lost on Harry Potter.

He was standing in a bustling Muggle department store in central London. On his left was his wife, Ginny, who was vibrating with pure, unadulterated amusement. On his right was Bellatrix Lestrange—recently paroled, aggressively confused by escalators, and desperately trying not to curse a mannequin.

And the reason for this unholy alliance? Bellatrix had a date. With Hermione Granger.

"If this glowing rectangle makes that noise again, Potter, I will reduce it to ash," Bellatrix hissed, poking a digital clothing rack with a manicured finger as if it might bite.

"It’s just a touchscreen, Bella," Ginny said, casually tossing a neon pink slip dress into Harry’s arms. "And remember, no magic. You promised Hermione you’d try the full 'Muggle experience.'"

Bellatrix shuddered, looking genuinely nauseous. "The things I do for that brilliant, infuriating woman. Fine. But why is he here?" She pointed a sharp nail directly at Harry’s nose.

"Because Harry has excellent taste in comfort," Ginny lied smoothly. "And he's our pack mule. Hold this, sweetie." She piled three more hangers onto Harry’s growing stack.

Harry sighed, adjusting his glasses, which were slipping down his nose under the weight of the clothes. "Look, can we just find something... normal? Hermione likes sensible things. Cardigans. Denim. Maybe a nice button-down?"

Bellatrix scoffed, her dark curls whipping around her face. "Sensible? I am a daughter of the House of Black, Potter. I do not wear cardigans. I require something that says, 'I am sophisticated, dangerous, and highly capable of overthrowing a government,' but, you know... casual."

"Right. Casual terrorism. Got it," Harry muttered.

The Changing Room Chronicles

Ten minutes later, Harry found himself trapped in the ultimate awkward purgatory: sitting on a tiny plush stool outside the women's changing rooms, holding a mountain of polyester and a leopard-print handbag that Bellatrix had refused to put down because she thought the pattern was "intimidating."

Every passing Muggle gave him a look of profound pity.

"Alright, let's see the first option!" Ginny called out, clapping her hands.

The curtain whipped open. Bellatrix stepped out wearing a skintight, neon-green clubbing dress with a slit that went up to her hip. She looked like a lethal, gothic glow-stick.

"The Muggle salesclerk said this is 'all the rage,'" Bellatrix said, narrowing her eyes at her reflection. "I feel exposed. If someone attacks me, how am I supposed to conceal a dagger in this?"

"Well, you definitely can't," Harry stammered, frantically looking at the ceiling to avoid looking anywhere else. "And—and Hermione is taking you to a quiet pub, Bella. You'll blind the locals. Please put on something with more fabric."

"Coward," Bellatrix snapped, but she retreated.

The next choice was entirely Ginny’s fault.

When the curtain opened again, Bellatrix was wearing an over sized graphic t-shirt that read "I'm with the Witch" with an arrow pointing sideways, paired with incredibly tight leather pants.

Ginny snorted so hard she had to lean against the wall for support. "Oh, Merlin. It’s perfect. It’s a literal pun."

"What is a 'pun'?" Bellatrix demanded, looking at the shirt with deep suspicion. "Why does it mention a witch? Is this a breach of the Statute of Secrecy? Potter! Explain this garment!"

Harry covered his face with his hands. "Ginny, stop torturing her. Bella, please don't wear that. Hermione will read the shirt, analyse the sociological implications of Muggle pop-culture interpretations of witchcraft for three hours, and forget to eat her dinner."

Bellatrix paused, considering this. "An excellent point. The bushy-haired menace does love a lecture. Next!"

The Final Verdict

After an hour of absolute chaos—which included Bellatrix trying to duel a security tag and Harry having to explain what a "push-up bra" was while wishing the floor would open up and swallow him into the Department of Mysteries—they finally found a compromise.

Bellatrix stepped out of the fitting room one last time.

The Date Outfit:

  • A tailored, charcoal-black trench coat (very classic, very Auror-chic).
  • A dark plum silk blouse that actually fit properly.
  • Sleek Muggle trousers and ankle boots.

It was elegant, dark, and uniquely her, without looking like she was about to attend a Death Eater revival meeting.

"Huh," Ginny said, genuinely impressed. "Bella, you actually look incredible. Hermione is going to short-circuit."

Bellatrix looked in the mirror, turning side to side. A slow, rare smirk spread across her face. "It has structure. It has menace. It breathes. I suppose Muggles aren't entirely devoid of intellect."

She turned her gaze to Harry, who was currently buried under a pile of discarded neon clothing, looking thoroughly traumatized.

"You," Bellatrix said, poking him with her foot. "The boy who lived. Go exchange your gold coins for this 'paper money' and purchase these items. My treating of the Granger girl depends on your speed."

Harry dragged himself to his feet, clutching the clothes. "Right. Going. Paying. Never speaking of this day again."

As he walked toward the cash register, he heard Ginny whisper loudly to Bellatrix, "Now, let’s go look at the Muggle makeup aisle. Have you ever heard of waterproof mascara? It holds up great during emotional breakdowns."

Harry picked up his pace, praying Hermione's date went well—mostly so he'd never have to do this again.

The Pub, The Panic, and The Polyjuice Scare

The Leaky Cauldron was entirely out of the question, so Hermione had chosen a dimly lit, violently hipster pub in Shoreditch. It featured exposed brick, craft beers with names like Desolation Angel, and absolutely zero magical surveillance.

Harry and Ginny were currently stationed three tables away, hidden behind an unnecessarily large chalkboard menu.

"Harry, stop gripping your pint like it’s a broomstick," Ginny murmured, taking a delicate sip of her gin and tonic. "You're drawing attention."

"She has a wand concealed in her sleeve, Ginny. I saw her slide it in there right after we paid for the trench coat," Harry hissed, adjusting his Muggle baseball cap. "If the bartender takes too long with the menus, she’s going to transfigure him into a coaster."

"Relax. Hermione can handle her."

Right on cue, the pub door chimed. Hermione walked in, looking windswept and breathless, scanning the room. She wore her usual sensible denim jacket and a knitted scarf. When her eyes landed on the corner booth, she froze.

Bellatrix was sitting there, looking like a gothic film noir actress. She was perfectly still, her dark plum blouse catching the amber light of the pub, her chin resting on her hand as she tracked Hermione’s movement with a predatory, yet undeniably captivated, gaze.

"Merlin," Harry muttered, shielding his eyes. "This is like watching a lion stalk a very clever librarian."

The First Date Protocol

Hermione slid into the booth across from Bellatrix, smoothing down her hair. Harry strained his ears, utilizing a subtle, highly illegal Muffliato charm that he’d modified just enough to eavesdrop without getting caught by the Ministry.

"You made it," Hermione said, her voice a mix of nervousness and academic authority. "And... you’re wearing Muggle clothes. Real ones."

"Potter forced me into trousers," Bellatrix said smoothly, though her eyes flicked around the pub as if checking for snipers. "He claimed my original choice—which involved an exceptional amount of neon green—was a 'safety hazard.' I suspect he lacks vision."

Hermione blinked, a small smile tugging at her lips. "I think Harry might have saved us both from a fashion disaster. You look... exceptional, Bella."

Bellatrix’s posture softened by exactly one millimeter. She smirked. "Of course I do, Granger. Now, what is the protocol for this ritual? Do we summon a house-elf, or do I have to violently interrogate that bearded man by the taps to get us a drink?"

"Neither! Please, let's keep the bar staff alive," Hermione said quickly, pulling out her phone. "We order on an app now."

Bellatrix instantly reached for her sleeve. "A dark artifact. I knew it."

"It's a mobile phone!"

The Stakeout Escalates

Back at the observation table, Harry was sweating.

"She’s reaching for her wand, Ginny, I'm going in—"

"Sit down, Harry," Ginny ordered, catching his jacket. "Hermione is laughing. Look."

Harry looked back over the chalkboard. To his utter bewilderment, Hermione wasn't dodging a curse; she was leaning over the table, showing Bellatrix the phone screen. Bellatrix was frowning fiercely, her nose practically touching the glass.

"So.. if I press this tiny picture of a basket, a man will bring me fermented hops?" Bellatrix asked, her voice carrying a mix of profound suspicion and reluctant awe.

"Yes," Hermione smiled.

"Muggles are terrifying," Bellatrix concluded, leaning back and looking at Hermione with a look that was dangerously close to affection. "They possess no magic, yet they have enslaved time and space to deliver alcohol to their fingertips. I respect the malice behind it."

"It's not malice, it's convenience—"

"It is dark magic, Granger, do not coddle them."

The waiter arrived a few minutes later, placing a pint of IPA in front of Hermione and a glass of red wine in front of Bellatrix.

Bellatrix picked up the wine glass, swirling it with menacing elegance. She looked the waiter up and down, her eyes narrowing. "Tell me, young man... is this vintage poisoned? Because if it is, I have a high tolerance, and I will make your death slow."

The waiter, a nineteen-year-old art student named Toby, stared at her. He looked at her sharp jawline, her wild dark curls, and the intense, terrifying aura she radiated.

"Uh," Toby swallowed hard, blushing furiously. "No, ma'am. It's an organic Malbec. It's... it's got notes of blackberry?"

"Excellent. Leave us."

Toby practically sprinted away. Hermione covered her face with her hands. "Bella, you cannot threaten the staff."

"I didn't threaten him, I inquired about his health and safety protocols," Bellatrix defended herself smoothly. She took a sip of the wine and shrugged. "Acceptable. Now. Tell me more about this 'Ministry Department Reorganization' bill you are writing to annoy the Minister. I want to hear how you plan to ruin Kingsley’s week."

Hermione’s eyes lit up—the universal signal that someone had just unlocked her favorite topic. "Oh! Well, it actually starts with the clause on magical creature labour distribution—"

The Great Escape

"Well, they're set for the next four hours," Ginny declared, finishing her drink and standing up. "Hermione is in her element, and Bellatrix looks like she’s planning a political coup as a courtship display. Our work here is done."

Harry looked at the happy, bizarrely matched couple in the corner. Bellatrix was listening to Hermione ramble with rapt attention, occasionally nodding with a bloodthirsty grin whenever Hermione mentioned breaking a bureaucratic rule.

"Yeah," Harry sighed, finally relaxing his shoulders. "They're perfect for each other. In a terrifying, deeply stressful kind of way."

As Harry stood up to leave, his phone buzzed in his pocket. It was a text from an unknown number.

Unknown: Potter. The trousers are acceptable. The blouse is acceptable. If you ever speak to anyone about the 'I'm with the Witch' shirt, I will find you. Have a lovely evening. - B.L.

Harry stared at the screen, a chill running down his spine.

"Ginny?" Harry whispered, hurrying out the pub door. "How does Bellatrix know how to text?"

Ginny just laughed, pulling him into the cool London air. "I gave her my old phone, Harry. Happy anniversary!"

The End.
