Sewing Resizing a pattern?

Hello,

Hope y'all are doing well.

I just got a few patterns off of Etsy to make dresses for my Raccoon doll. I'm very new to sewing and have never made doll clothes. I know I can resize patterns and that's why I got these because they are for Iplehouse F.I.D (old body) with medium size bust. My raccoon doll is the glamorous body with the large bust.

I am trying to find the F.I.D measurements so I can try converting them but I'm having a hard time finding them for some reason.

Help would be much appreciated!

Thanks

 

Thank you so much! I hadn't even realized that was a section lol.
Even though I've been a member for a long time I haven't gotten into using this site that much yet. I want to use it more now that I've started up the hobby again.
I really appreciate the help!
