I would imagine that B!D would convince Kara do dress up as Captain Marvel much to Kara's and Alex's dismay. And vlogs it for the masses. But also call Kara, Carol for the next week to mess with her. I had something similar happen to me before.
I love this you don't even know!!!
Carol and Kara are very obvious buds. Fight me.

"KARAAAAA!!!!"
The door burst open as the youngest Danvers sister walked in carrying what looked to be a suit bag. "Oh Alex! You're here too! Great!"
Both her older sisters looked over, confusion written over their faces. "What's up?",
"Try this on!"

Twenty minutes later Kara walked out wearing a cheap costume, she wasn't amused. "Y/n I can't walk around like this."
Alex was next to pipe in, "She definitely can't walk about like that!"
"But it's for a vlog, please guys, just for a couple hours please. Please."
The older sisters shared a look, "I mean I guess Carol wouldn't mind?" B!D's smile only grew, an excited squeal left her.
They spent the day walking around vlogging. The following week B!D walked into her sisters apartment "Sup Carol."
