GOM + Hanamiya + Himuro + Imayoshi reaction when their s/o goes to classes in clothes they (s/o) stole from them? I'm sorry if it's too much characters :)
Generation of Miracles
Akashi Seijurou: Akashi knew from the start that you’d taken his shirt, but when he saw you in it he felt it suited you much better than he expected. He would tell you that you looked lovely, and hand cupping your cheek as he brought your attention to him.
“Hopefully you’ll give me the honor of removing it later.”
Aomine Daiki: Aomine can’t help but feel a little excited at the sight of you, since it was his shirt that he couldn’t find last night after your escapades had ended. Seeing you in it causes all the memories of the previous night to come back, which only gets him fired up and ready to tear it off.
“You can keep it… But only if we can re-enact some of last night right now.”
Kise Ryouta: Kise would be thrilled to see you in his clothing, squeezing you and telling you ow you are, drawing as much attention to it as he could. He would tell everyone you were wearing his clothes proudly, with you getting embarrassed at the people assuming something sexual had been involved in getting his clothes.
”(Name)cchi is wearing my clothes! It’s like we’re finally an official couple!”
Kuroko Tetsuya: Kuroko blushes pink initially but hides it well, complimenting you and saying it looks better on you than it does on him. He humbly requests that you give it back the next day, which in actuality was just an excuse to have his piece of clothing that now had your scent on it back.
“It looks better on you than me, you’re good at making anything look good, (Name)-chan.”
Midorima Shintarou: Midorima would be caught off guard, as he’d been wondering where that particular shirt had went. He gets you alone as soon as he can, asking you what you think you’re doing, embarrassed to see you in his clothes and worried about something recognizing they’re his. You tease him, telling him its your lucky item, which he calls you out on since he knows it’s not.
"It’s not your lucky item for the day- What do you mean how do I know? I just do!”
Murasakibara Atsushi: Murasakibara never really thought much about fashion or the way he dressed, and didn’t tend to keep track of all his clothes, so he didn’t notice his shirt went missing until he sees you in it. He knows it’s his from it’s clearly large size, getting embarrassed at how cute you look, thinking about he wants to get cute noises out of you now, too.
”(Name)-chin… I have more clothes for you to wear.”
Hanamiya Makoto: Hanamiya would have noticed his shirt gone immediately, unsurprised when you walk in wearing it, smirking to himself about how it was perfect because it marked you as being all his. You considered it more of a trophy proving you owned him since he clearly wasn’t objecting to you wearing it (until he corners you later, telling you it needed to go, showing that it had clearly frustrated him more than he originally let on).
“I prefer you without clothes, but wearing mine is good, too, if I don’t have a choice in the matter.”
Himuro Tatsuya: Himuro would have given you the shirt to wear home when you requested it, as you had said it’s what boyfriends do for their significant others. He wouldn’t mind, seeing you in his clothes making his heart warm immediately; he would pull you close as he whispers that you look stunning, offering to give you more of his clothes if you wanted.
“Seeing you in my clothes makes me happy, if you ever want to borrow more… don’t be afraid to ask.”
Imayoshi Shoichi: Imayoshi would see you first in his attire when you run into gym, calling out to him and pointing out his shirt on you and asking if it looks good on you. He’s a little surprised at first but leans down and nuzzles your neck, calling you a tease and accusing you of trying to provoke inappropriate thoughts during practice.
“You should know better than to tease me… but you’ll learn your lesson when we’re home.”
