Hi usually any rompers jumpsuits etc are tricky for me because if I order my bust size it's too big in the hips.... With this because of the stretch and mostly nylon and the reviews I read I decided to get a Medium..... because of the helpful reviews....( thanks people for actually adding helpful information on this products reviews) I decided on a medium because people said size down..... it fits perfectly this one with nylon and spandex because of the stretch.... Bust 41-42 Waist 31-33 Hips 40-41....Long Torso.... this fits in the torso too .. doesn't cut me off at the bust... I usually like more cotton but this nylon one I am not mad at it..... Short length is good too not short like mid thigh on me.....I am 5 10".... I am going to wear it up under a crochet long cardigan I bought with brown tights under and tall boots! . I got it on sale... actually half off! So worth it..I would say it's worth the regular price too...some things are not but this i would pay the regular cost ... People please put as much information as you can on reviews so it actually helps everyone picks sizing.....I really go by reviews myself especially because you don't get your dollars back here for returns.....that way it saves so much hassles..... Thanks
