Definitely high waisted.
Im 130-135 lbs and I guess you can say my lower body is kinda thick. Based on reviews and the sizing of my other jeans, I ordered a size 5 and before I could even pull it up to my thigh I knew they were gonna be tight. They do fit but I would prefer if they had more space or stretch. Maybe its because I need to let them shape to my body a bit more but this is my first impression.
