Controlling Parents

I am 18 years old, graduated, work a full time job, and am a freshmen in college and my parents still think they're in charge of me. Granted, I do still live under their roof while I do my online college courses, but OH MY GOSH. My mom still leaves me a list of chores to do on my days off while she is at work, my boyfriend isn't allowed at the house unless my mom or step dad is home, my mom still texts me constantly asking me where I am and what I'm doing and when I'll be home, my mom decided I am not allowed to spend the night at my boyfriends house anymore because "accidents happen" and if I do then she will kick me out, and my step dad still tells me I'm not allowed to wear shorts out of the house and tries to control what I wear. I am not a vulgar girl in any way AT ALL! I don't even like wearing v neck shirts because my boobs are too big, and I don't like when you can see them. I just don't know how to get them to understand that I am not 15 anymore and they can't control every little thing I do.
