Chapter Text
He knows it from the sparring, from the holding Bakugou back, from the occasional cuddling whenever he slept over, from the moments where their arms would touch when they stood beside each other, from the hugs Bakugou pretends he hates.
Bakugou's height is similar to Kirishima's anyway, just a bit taller.
Kirishima knows Bakugou's arms were a tad longer too, because he stands too close sometimes when he wanted to imagine what it would be like to hold Bakugou's hand.
The waist, chest, and hip measurements were more tricky, but Kirishima tried his best.
Because he always held Bakugou back, hands on his chest, around his chest, around his waist, or on his waist (it depends on the situation, really).
And when they sparred, that one time Bakugou pinned Kirishima down and sat on his stomach, and Kirishima placed his hands on Bakugou's hips to get him off.
Then the cuddling and hugging, Kirishima's favorite references for Bakugou's suit measurements. It's not often, but it sticks to Kirishima's mind always.
It starts with Kirishima's hand on one side of Bakugou's waist. If approved, he puts his other hand on too and wraps his arms around it.
Their cuddles are almost always Kirishima being the big spoon, holding Bakugou as close to him as humanly possible, again his arms around either Bakugou's waist or chest.
Sometimes Bakugou turns around to wrap his arms around Kirishima, but that's not a reference for the suit so Kirishima disregards it.
It was awkward getting the suit made, Kirishima only giving Bakugou's measurements through hand gestures and relative to his own body.
He was afraid it wouldn't fit but, holy shit, it fit so well when the time came.
Kirishima is proud for retaining all the information he needed.
Bakugou looks at himself in the mirror, impressed.
"You look really good, bro. It fits nice!" Kirishima exclaims.
The blond stares at him on the mirror and deadpans, "How did you even get my measurements, hah? I bet you called my parents, you hair-for-brains."
Oh no... Kirishima was hoping Bakugou didn't ask. "Ah... Well..." He starts.
"Well?" Bakugou turns to face him, raising his eyebrows.
"Well... I just gave them some... Approximations..."
"Based on what?"
"Er... Just from..." Kirishima puts his hands up and set them a certain distance apart, "This is your chest," he moves his hands closer, "Your waist," farther again, "Your hips."
Bakugou looks at him in disbelief, with a hint of amusement in his eyes that he's trying so hard to hide, "Fucking creep." He mutters, but Kirishima catches the small smile on his face when he turns towards the door, "Let's go."
That night, after fighting the villains, having dinner with their classmates, and showering, Bakugou lies down on the one bed in their hotel room and signals Kirishima to lie down too, "C'mere."
"But it's still early..." Kirishima tilts his head to the side, confused
Bakugou rolls his eyes. "I'm gonna memorize your measurements too. Come here."
He insists on being the big spoon this time.
