I'm kind of cheap. And I like used stuff. So I had a little shopping urge and managed to address it for a mere 780 yen. Thanks, Thank You Mart!
Some other thrift stores in my area:
Kinji: I've never found something I liked there.
B-style(part of the Book Off kingdom): The hundred or two hundred yen racks are cool for a quick skirt.
Thank You Mart: A small, but seemingly more carefully cultivated selection. Everything is 390 yen!
And I always love the city-run Machida Recycling Culture Center. Even though I don't usually find clothes there, I find other random cool stuff sometimes. Loads of zippers. Vintage stickers. Oodles of kimono cheap that make me wish I could quilt or do sakiori. Gocco stuff. Etc.
