What are some cheap unknown stores for a teenaged girl?

Online my favorites are Karma Loop, Cutxpaste, 80's Purple, and Paper-Doll. The price point I would say is kinda high and not like chain stores. Etsy is a great place to go for independently produced items (Cutxpaste is similar). Second hand stores are also great. I also don't know which "scene" you are talking about. There are so many "scenes"...I'm with the fine art student scene so I'm just answering with my mindset of "scene"
