Just cruisin through and saw your question. I have four daughters so I've made a lot of doll clothes
There are several excellent sites that have reborn doll clothes patterns, I'm not sure how to post a link but if you google you will find them.
shifio doll designs
cute n cuddly designs
kadie jade designs
babydoll handknit designs
These should give you lots of ideas, I've made some beautiful baby gifts from shifio designs and handknit babydoll designs. The sizes range from 3" dolls to 0-3 month old babies.
