She's definitely in the size bracket as the Dollmore Lusion's, which are 79cm. Playdate's are about 81cm after conversion~ I don't know specific measurement differences, such as chest circumference, between the two but I'm sure there are some good options that would work in what Dollmore offers.
Full outfits are far more expensive at Dollmore, but there are some basic item options and simple dresses~ Here's the link to their Lusion clothing category:

I also know a lot of owners for Lusion's and Trinity's look for shoes in the children's shoe department sections. ^_^
