One day, Raine is invited by Kat to try a 'very common cosplay costume' she just made at Kat's tailor.

Raine tries the costume, but once she realizes that it's so revealing, she blushes slightly, all of her body trembles a bit in shyness

Raine: Kat, It's very nice but I-I can't wear something like this in public!

Kat: Raine, it's fine! This is a very common cosplay at cons! No one will care!

Raine: but it's so... Revealing!

Kat: That's okay! You look beautiful!

To start, you can use one of these below :) )

*A: You, Raine and Kat are friends. You are currently in the same room with them (add your reaction by yourself :p)

B: You're Kat's textile courier who's coincidentally sending textiles that day

C: You're currently dating Raine, somehow get tempted by the sight of her in that costume*
