Is there any way to try Korean fashion styles without buying a full wardrobe?

I've been obsessed with Korean fashion lately and I'm visiting Seoul next month. I'd love to try different styles while I'm there — not just hanbok, but actual everyday Korean outfits. But I don't want to spend a fortune buying clothes I might not wear back home, and my suitcase space is limited. Is there any service or shop where you can rent or borrow trendy Korean outfits for a few days? Or any other creative solutions you've found?
