Yondu finding out about the tradition to dress up for Halloween so he asks Peter to help him dressing up as Mary Poppins (obviously not knowing a thing apart from "*he*'s cool").

"Oh come on, it's nearly Halloween" you moan to Peter, "We should do something"

"Like what? We're the only two Terrans here. No-one even knows what Halloween is" He said, adjusting his headphones and he lounged back.

As if on cue, Yondu appeared in the door way, "Wha's 'allaween?"

You smiled at your partner, "Hal-low-een" you said, trying to get the right pronunciation for him, "It's a Terran holiday"

"Like Chrismis?" he asked, coming over to lean on the back of your chair, kissing the top of your head as he did.

"Yeah, like Christmas" you smiled.

"Yeah, you dress up and eat candy and tell ghost stories" Peter explained, turning up his nose at Yondu's display of affection towards you.

"D'ya wanna have a hallaween party, Darlin'?" Yondu asked, his hands now rubbing your shoulders.

"Yes!" You squealed excitedly.

Peter groaned. Yondu said, "Alright then Princess, you go find yourself somethin' ta wear, an' I'll take care of the rest w' Quill"

Peter shot him a look, "What"

"Anythin' fur ma girl" Yondu continued.

You laughed, and grinned at him, "Thank you Sweetheart"

"Yer welcome" He winked.

Peter let out a deep sigh. "Ew"

A few days later Peter came to you, "Y/N, you know the Halloween party thing?"

"Yeah"

"I need help"

You raised an eyebrow, Yondu wanted to keep the whole thing as secret as possible to surprise you. "With what?"

Peter looked you dead in the eye and gave a low sigh, "Yondu's costume"

"And…?"

"He wants to be… Mary Poppins"

You burst out laughing, "Oh!"

"How the Hell am I meant to pull that off? He doesn't even know who it is! He thinks it's a guy for a start, and that 'he's cool' - seriously, Y/N, what am I meant to do?"

Eventually you managed to stop laughing, "Uh, adapt it - keep the important bits and change the rest"

"Like?"

"Like keep the umbrella and the bag and colour scheme and make it a suit instead and lose the hat" you were still giggling at the mental image of your boyfriend in the full skirt, corseted waist and hat.

"But where am I meant to find any of it?" Peter asked, still vaguely distressed.

"We're docking tomorrow for supplies, go get the stuff then"

"For tomorrow night? What if I can't find it?"

"Peter," you said, taking him by the shoulders, "it's not like he's going to know the difference anyway"

The next 24 hours passed slowly. You had to pretend that you didn't know about Yondu's costume and that was slowly driving you mad, because all day he'd keep playing at making you guess what he was going to wear - and obviously you couldn't guess right.

You were keeping your costume secret too, for no other reason than teasing Yondu. Not that he would understand what you'd be dressed as, but you found it fun to wind him up. You'd managed to get the material together, and make it from scratch - it wasn't like you were going to find a Star Fleet uniform anywhere in space, ironically.

You were happy with how it had turned out, a little on the short side, due to lack of fabric, but that didn't really matter. Yondu may not understand what it was meant to be, but he'd love it all the same; you were just pleased you'd managed to find boots to go with it.

You were getting ready for the party, dress and boots on, hair done, make up finished. You had to admit, you looked pretty awesome. Yondu was getting ready in Peter's room, so you couldn't see his costume until the last minute. How in the galaxy Peter would be able to explain to him what he was wearing, you didn't know.

There was a knock on your door. You got up, straightening out your dress, and opened it to see Peter, dressed like one of the Ghostbusters. You laughed, "Awesome outfit"

"Damn, you too - okay, I was told to go get you and Yondu won't be long"

"Okay" you smiled.

Yondu had done a great job of putting the party together, even though there were so few of you. The rest of the guardians were there, dressed as the rest of the Ghostbusters (though you were sure they had no idea what that was), except Groot who seemed to be dressed as Rocket. Kraglin was also there, as some kind of witch (not wizard, definitely a witch).

They greeted you both as you entered the main living space in the Milano and a few minutes were passed checking out each other's costumes, before you heard Yondu behind you, asking louding, "So, what d'ya think?"

You turned to see him, and your jaw dropped.

He looked good, really good. "Wow" you muttered.

He grinned, 'Damn, girl, I got ya speechless?"

The costume was incredible. The white dress shirt was stretched over his chest, with a red bow tie at the collar. Over that he was wearing a blue jacket, the clung to his arms. And the boots, scarf, hat and umbrella finished it off perfectly. "You look amazing" you told him.

"Don't look bad yerself, Darlin'. So, d'ya know who I am?"

You smiled widely, "You're Mary Poppins"

"That's right" he laughed, "And I don't know what you is, but yer lookin damn hot in that dress"

You heard a quiet groan from Peter and you laughed. This was going to be the best party of your life.
