Random scenarios that came to mind.
Y/n: Bucky! look at uncle Sam! Isn't he pretty?
*bucky looks at Sam who had makeup all over his face*
Buky trying not to laugh: yeah he looks great, good job kid
*Y/N runs away looking for their next victim*
Bucky: I can't believe you let them do that to you.
Sam: you're just jealous they didn't ask you. I look amazing.
Bucky: no. You look ridiculous.
*a few hours later he finds y/n putting bows in buckys hair, looking at his new pink nails*
Bucky: Shut up.
OR.
Bucky: no. You look ridiculous.
Sam: uh bucky, behind you.
*bucky turns around to see y/n looking upset*
Bucky: I'm sorry kid. No don't cry. I'll let you do mine.
*y/n's eyes lit up as they pulled him to a seat soon his hair was covered in bows and clips and his nails were hot pink*
Sam: it's fun huh?
Bucky: I've never felt prettier.
Idk which I like better 🤷🏻♂️
