staring?

so today i was at the mall with my sister and she and i found a couple dresses and shorts and stuff for me to try on, now i’m a bigger girl, i don’t like shorts and short dresses and stuff like that. so we went into the fitting room and everything i tried on there was this one girl who would just stare at me with this look on her face.. now i get it if she thought what i had on looked pretty or whatever. but at the same time i just wanted to look at her and be like take a picture. i’m going way out of my comfort zone to try on things that look nice and i feel good in... maybe i’m crazy but is it just me who gets very insecure and just says forget it an put things back?
