And by looking at the jeans irl, are they all very tight fitting? :( joni and jamie are very nice! Binx look nice too! Im actually very petite and has a very small waist hahaha but i also dont want the jeans to be very tight from my thigh area to my ankle. I need some advise hahaha

Yeah they are quite tight fitting but they are super stretchy. You should try them on to see if they are comfortable for you. You can try the Topshop petite range to see if those fit better!!!
