The photo above shows what Cecil's disguise looks like. As for Carlos's disguise, he just wears a yellow turtle neck, a dark brown trench coat, and dress pants. You, on the other hand, aren't lazy (At least, not lazy when it comes to designing clothes for any scenario) and decided to wear this for your disguise:

That's all folks, Author out~

»(Y/n)'s POV«

When we were in the Strex Corp. headquarters, I took one look at the boys' disguises and said "Really boys, you couldn't even get a little creative when it comes to your disguises?" "Well, sorry if we aren't total fashion freaks like you!" "Ouch. Harsh words, Cece. Harsh." I said, putting a hand over my heart "Stop calling me that! It's embarrassing!" Cecil said through gritted teeth "Why not? It's really cute." Carlos replies. "You two are literally perfect for each other." I said, which made them blush. "But enough with the chit chat! We've got a mission to do!"

~~~~~~~ Timeskip after the plan and how you guys get in b/c the author is lazy ~~~~~~~~

My face hurts from smiling so much. How do these people even manage to smile for so long?! I entered a hallway has pretty much no one. I noticed a mural of the 'smiling God' that they worship. Ugh, there's no time for this (Y/n)! You gotta get to the– I bumped into someone and fell backwards onto the ground. "Oh! I'm so sorry! Are you alright?" said the person I bumped into— holy mother of cheese balls he's hot. I snap out of my daze, heat rising to my cheeks, and I take his hand "Thanks." I reply to him. I look at the mural and, without thinking, I said "What does it look like?" "What does what look like?" the man said "The smiling god's smile. What does it look like? Is it a smile of happiness? Is it a smile of sadness? Or is it full of regret, anguish, and/or insanity? I guess we'll never know, huh." I said, still not thinking. He looks at me, shocked. Realizing what I said, I quickly put on my all-too-cheerful facade. "Oh, forget what I said. I shouldn't ha–" "It's alright." wait, what. "Eh?" "I said it's fine. It's just I.... I never really thought about that."

He smiles at me "You're really something, y'know that? I'm Kevin, by the way." he sticks hand out. I take and shake it. (Author: ooh dat rhymed) "I'm (Y/n), nice to meet you Kevin!"
