sororities and weight

hi! i'm rushing in the fall and i'm super nervous mostly because i'm really self conscious of my weight. I would say i'm a solid size 5, about 130 pounds. I've heard a lot of stories about during rush the houses really care about how skinny a girl is, and even one story about how much room there was when the girls walked through the door. Of course i'm not trying to join a house that is superficial af but i'm curious if girls who aren't super skinny can get into the top houses too? i'm super hard on myself about my weight and its one of the reasons i'm so nervous about rush this fall, because i've been told how rush is really fake and all about looks (from other friends who are in top/middle and bottom houses). maybe i'm just stressing myself out too much but just any advice to calm my nerves would be really appreciated! my top choices so far from friends in houses are middle houses and 1 upper mid/lower top so I don't want Kappa or any of those but just a good house with a mix of social life and good sisterhood. any advice to calm my nerves is really appreciated!!
