I told you to go right

When we arrived back, a huge cheer arose. We six stallions, who had looted a bunch of old armour that had been buried in the ground, had just fled from a gigantic Thresher, and yet they cheered us? I gave a few nods to ponies, a fake smile on my face, before it began to die down. We simply stood there, surrounded by citizens of Ponyville, looking slightly awkward. Finally, Ebony stepped forward and cleared his throat.
"Yep...err...we're back...yeah." he said quite loudly. Suddenly, from the back of the audience, somepony blurted out just what I didn't want them to.
"SPEECH!" the stallion yelled. Soon, a few more joined in, shouting 'SPEECH' in a sort of cacophany of shouting. And, within a few minutes, I got bored and wandered off to go get ready for my night out. Please don't ask, please don't ask, please don't as-
"Thunder! Where are you going?" somepony called after me. I paused, contemplated answering, before ignoring it and continuing to the house. I heard clanking hoofsteps clank up to me from behind, so I turned: coming face to face with Fire Trail.
"Ehm, Thunder?" he whispered.
"Yeah? Could this not wait until we get home?" I replied with a sigh.
"No."
"Fine, what?"
"Well, you can't get ready without any clothes..."
"And?"
"You don't have any clothes..."
"And?"
"Well, the thing is you said Princess Luna wanted you to arrive in clothes."
"Where is this even leading, Fire?"
"Look, just ask Rarity for some clothes. If not, just clean up the armour you're wearing and just wear that."

"I'm likin' the last option." I grinned, before turning and trotting home. Behind me, an exasperated Fire muttered that I was being a dumbass and trotted back to the crowd.

Before I started to clean up and polish off the armour, I made a mental note to check for previous owner names, armies, platoons, anything that might tell me who owned it originally. For all I know, Celestia herself may have worn this. Unlikely though, because, not even joking, her ass was probably perfect back then, so my stomach would be being crushed. Not wasting any more time, I turned the tap on and ran the rusted chestplate underneath the running water. I waited several moments before scrubbing away at the rust with a wire brush and soap. I was surprised the former of those two objects even existed, actually, but I ignored it. Already seeing a difference between where I had and hadn't scraped off the iron oxide, my hoof pressed even harder and cut through the rust like a katana through an innocent Japanese farmer. Just before I could begin on the boots and sword, a voice called out. Southern accented, female, and presumably the owner was trotting at a pace, I assumed it was Applejack.
"Thunder!" she called out. "Rarity needs t' see y'all!"
"Alright." I replied, shutting off the tap, putting the stuff inside the house, before leaping the fence with a wing-propelled burst and going at a remotely swift pace towards Applejack. The cowpony was smiling, so I'm assuming this was bad.
"Hey y'all." she smiled, turning and trotting alongside myself as we both headed to Rarity's. "Rarity said she owed everypony a favour for savin' her, and she thought y'all would need to use your favour to prepare for your date tonight."
"It is not a DATE." I firmly stated. "It is simply a meeting. And I was considering just wearing the metal boots and chestplate I found back on the mountain, both polished to a shine."
"Y'all really wanted to wear that old stuff?" Applejack groaned. "To be honest, I admit it'd look nice all shined up, but it might take y'all a while to get it off when...y'all and Luna."
"Shut up." I growled. "Lest I alert the girls to you and Solar."
"Alright tough guy," she laughed as we went past the Town Hall.."Y'all win this round. Just don't be surprised when the mares are in season. None of 'em will be gunnin' for you, I can tell ya that much."
"That shit happens?" I asked.
"Y'all and your virginity wouldn't last two minutes when that time comes. But your friend Sky? Apparently he's after Rainbow."
"Far as I know." I snorted as we arrived at the boutique. It seemed bigger than I remembered it from my few times I'd went there out of boredom. Opening the door, I cautiously trotted inside to see Rarity working feverishly away on the sewing machine. Her mane was dishevelled, red rimmed glasses were balanced on the tip of her snout, and she seemed satisfied with what she was doing. I coughed to gain her attention.
"Hello darling." she greeted from the sewing machine, not averting her eyes from what she was doing. From what I could see, it looked like a tie. "I'll be with you within une momento." I rolled my eyes at her display of knowledge about other countries. She finished off the tie, before standing and looking at me. "Thunder! You're here. Goodo. Now, I believe you have a date with a mare, hmmm?" she smirked.
"Yes," I replied, worried by how close she was leaning. "Princess Luna, to be precise."
"Ooh, that makes it even more important you look your very finest!" Rarity squealed, rubbing a hoof in my mane.
"Very." I rolled my eyes.
"Well, I decided that to thank you, I shall make you a fine suit for your date. No charge, so enjoy!" Rarity gestured over to a ponnequin wearing a crisp black tuxedo, black tie, and fine shoes, along with a black fedora. I grinned.
"Nice one. Thanks for this." I smirked. I looked at the clock. 5:00, enough time to get ready, go to the library, and chill for an hour and a half.

"Not a problem, dear. I am the element of generosity, after all!" Rarity laughed. "Go get changed in the cubicle provided: the fruits of my effort are to be observed at last!" I followed her advice as the suit was levitated into the cubicle, hung on a rail, before she pulled the curtains. "Enjoy!" she called as I began to put the shirt on.

I pulled the curtains, satisfied with how I looked, and received a small clap from Rarity.
"Nicely fitted, Rarity." I commended her. "I never gave you my size? Or, unless you snuck in whilst I slept." I laughed.
"Oh, stop it." Rarity blushed. "And anyway, I sized you up the first time we met. You know, when you and your friends trotted in, looking amazed by everything."
"Ha, look how far we've come." I laughed.
"Yes, originally you weren't exactly Fancy Pants, but now: you're about to go for an evening with Princess Luna! You grew up so fast."
"I suppose. And this is free?"
"Of course: Element of Generosity, and all that."
"Well, probably gonna stop off for some cologne on the way to the library. Need me to buy you anything whilst I'm in Canterlot?" I asked. Rarity looked confused. "Just repayment for this: I can get you some fabrics and stuff on the way back. Need any?"
"Err...no thank you, darling. Just enjoy your evening. And if it gets to the bedroom, be sure to enjoy THAT, too."
"Oh, I loathe your incredibly good innuendo drive." I sniggered as I left the door. "I'll try to enjoy the latter if it happens. Bye!"
"See you soon! Be sure to recommend my shop to any Elite you might meet!"

"I will! See ya!"

This shop was pretty awesome. It sold cologne, potions, artifcats of value, and in the back, what appeared to be neurotoxin. Not sure if the latter was legal, though.
Legal or not, either way I was leaving with some cologne. As soon as I entered the door to 'Chemical Composition's Colognes and Perfumes', I headed right, looked on the shelf, and one immediately caught my eye. Labelled 'The First Date', the container was in the shape of a di-NONONONONONONONONONONOOOOOO!
I immediately moved away and ran from the shop. AS FAST AS I POSSIBLY COULD. Eventually, when I got about 50 metres away, I slowed, and began trotting at a steady pace to Twilight's library. However, just as I went past the café, a female wolf whistle was directed towards me, followed by female giggling. I smirked, looked over, and saw Colgate, Berry Punch, Bon-Bon, Lyra, and Vinyl Scratch sat at one table. I assumed this was the 'girly meet' that Colgate had pissed me off with, and went over.
"Well well, look at you!" Colgate giggled as I approached. "Where you off to? You seeing a mare?" The other girls around the table oooh'd at the comment.
"Ah, yes." I replied.
"Who?" Vinyl asked. "Is it Octavia? She seems like a perfect match for you."
"Higher up in the social ladder." I said casually. Berry thought for a moment, before getting an idea.
"Ooh, Upper Crust? She seems like you AND higher in the ladder." the purple mare said. "Is it her?"
"Even higher..." I muttered as I grinned. The girls around the table seemed impressed.
"Fleur de Lis?" Lyra asked.
"Top of the ladder. Runs everything."
"W-What...?" All the girls stuttered at once. "O-One of the P-Princesses? You're joking."
"No." I replied. "Princess Luna has decided to invite me up to Canterlot for the evening, as thanks for returning her from Nightmare Moon."
"Woah..." Vinyl murmured.
"I know. That's what this suit's for. And girls..." I laughed. "...you would not BELIEVE some of the implications I'm assuming." That seemed to unfreeze them as they began laughing.
"Wow, first you were a nutjob nopony wanted to be near, now Princess Luna might be interested in you. Lucky stallion." Colgate smirked. "And who knows; maybe the future holds a 'Prince Thunder Mustang'?"
"Probably not." I snorted. "Bandits'll get me first."
"Or Terramorphus the Invincible." Bon-Bon laughed.
"Ha ha, utterly hilarious." I rolled my eyes. "And besides, that thing is bloody terrifying."
"Sure he is..." Vinyl trailed off. "Well, enjoy yourself tonight, Thunder. If you know what I mean."
"Oh my god Vinyl..." I groaned as the girls burst out laughing.
