I’m looking for good clothing websites for a teenage girl?

I’m doing some (ok, most) of my school shopping online, and I’m having a hard time finding what I need. I’m tall and thin so if the site doesn’t have a size chart I’ll need some help with that, sorry.
I’m looking for:
- basic cotton tshirts (no designs, in lots of colors, short and long sleeved)
- thermals/henley’s (I know I spelled that wrong but if you know what I mean I’d appreciate it!)
- navy blue/white striped tshirt. I can’t find one anywhere!
- plain hoodies (pullover or zip up)
- knit/crochet beanie like the one my avatar has, my friend borrowed mine and lost it ):

I’m on a budget of about $150 give or take, but I want to get lots of clothes since I donated pretty much my entire closet.
I’m picking best by the person whose stores I buy most stuff from. (:

THANK YOU!
