I'm 5'7" and my waist is currently 27", I fit really well into size 3, but probably because I have very little in the hip department. Hopefully HRT will help fill me out there at least a little (been on it for only 1 month so far), but my mom has very small hips too so I'm not expecting much!
Fingers crossed, I have always wanted hips- since I was 6 years old 😀
