wearing boyfriends clothes

Sarah
I really want to wear my boyfriends shirts. He does not own a single jacket or hoodie so that's not an option 😒 should I just ask him if I can wear one of his shirts or should I try to make a joke about it or just grab one and put it on? I'm worried that he might say no if I ask him but I'm also worried if I just put one on without asking, he might get mad (which I doubt would happen, he'd probably just be like that's my shirt can I have it back).Â
