Todomomo

Both. They both can decorate pretty well

Kirimina

Kirishima has some sense of fashion, Mina's dorm room was atrocious. Kiri had to decorate.

Miruhawks

Hawks has his own modeling agency. He probably knows how to decorate pretty well.

Iidamei

Both. Believe it or not, Mei actually can furnish homes. Her dorm isn't even messy because she hardly goes home, she stays in the workshop a lot.

Kamijirou

Jirou. Kaminari has been banned from Home Depot

Dabi x Toga

Neither.

Nejitama

Nejire would have the entire home be pastels if she got her way. The house is mainly beige, light blue, and a grey color.

Mt.Kamui

Both. They planed together.

Ryushot

Both of them picked out paints and the couch. She got to choose the throw pillows, blankets, and bedsheets though.

HitoRei

They went for a grey color. The couch is black with purple, grey, and white throw pillows. She mainly decorated though, he just helped paint. Her quirk was hella useful for putting furniture up.

Tetsukendou

Kendou had to. Tetsutetsu can not do that or the house looks like a wrestling arena
