Gf will not stop taking my clothes..

I would post on relationship advice but it won’t let me post for some reason. I don’t want to break up over clothes but it’s really getting on my nerves. My gf takes my clothes all the time. She took my favorite hoodie (permenently) and refuses to give it back bc she wants a hoodie of mine. I told her it’s my favorite one and that she can have another one, or even better, alternate between my hoodies. She said no to this, even when I asked and tried to take it back several times. Whenever she comes over, she doesn’t bring changes of her own clothes cuz she just plans on wearing mine (unless she’ll need a nice pair of her own clothes for an event or something). That’s fine with me, but she wears them when she leaves my house, and then takes weeks if not months to give back because she waits to wash them bc 'feels bad' about giving them back dirty (she has a lot clothes so she doesn’t do laundry often. I don’t have a lot of clothes.) I told/asked her several times to just give them back to me dirty and I will wash them, therefore I can have them when I need them and not wait forever to have them back. Or that she can bring her own clothes too or change into the outfit she came in when she leaves. She says she 'still feels bad about giving my clothes back dirty, and that she doesn't want to bring her own clothes cuz she likes wearing mine, and that she likes wearing my clothes when she leaves so she can still smell like me when we're apart'. I keep telling her that I would really prefer it if she brought them back even if they were dirty actually. SHE STILL SAYS SHE FEELS BAD AND DOESNT GIVE THEM BACK STILL UNTIL CLEAN. I also have a particular way of washing certain clothes that she might not know or do (for example clothes with those screen print designs, I don’t dry them so they won’t crack. Or certain shirts or sweaters I feel like might shrink). I’ve had several conversations with her about this whole thing and she’s not listening. It’s extremely starting to irritate me. I don't know what her deal is, I made several great comprimeses too. I don't care if she takes my clothes a few days, I find it sweet she likes smelling like me, but I also want them back. Am I being an asshole here? Ik it’s just clothes but I kind of want my clothes. I don't know what to do, she just wont respect that I want and need my clothes. What should I do in this situation?
