B.F.C. INK? What size tinies do these clothes fit?

Some of the larger BFC clothes fit slim SDs. My Souldoll Hye can fit in tops and skirts/shorts, and a friend's Luts girl can fit in some of the tops. Plus, the plastic shoes for the large girls fit SD feet! They look like jelly shoes and are totally adorable.

 

Thank you, this BFC Inc. Doll topic is informative; I have an Only-Doll, XuanYan (msd size).
