Junior sizes are a slimmer cut and typically fall between the misses so a size 3 jr would be a misses 2 or 4. Misses are a little fuller cut so I would suggest the smaller size in misses.
the sizes
PETITE IS FOR SHORTER WOMEN
petite sizes are for shorter women
She would wear a misses 10 or 12 depending on the fit because junior sizes are cut differently than misses sizes.
Womens's are the plus sizes and misses are the in shape one. I have no Idea why the separate the womens from the misses in my own opinion I believe that women's and misses are all the same things.
junior sizes are a little more bigger like for pre teens and kid sizes are for 10 or smaller
Misses sizes are for heavier women or women with larger bodies and tall sizes are just longer. Sometimes the two body types coincide.
18W is in Women's sizes, (fuller cut) and 18 is in misses' size (slimmer cut).
Junior clothing sizes are for teenagers and small adults, and therefore they are smaller than regular sizes. Usually they are 2 inches smaller in the hip and in the bust.
Misses are for people who have a more slender, skinnier frame and waistline and are technically geared toward the teenager population who are still growing. Women's sizes are for the older woman with the curvier figure (not to be confused with overweight).
