These four pieces are for a 6-9 month old baby girl. I purchased all of these myself for my daughter. 

The set includes: 

Pink zippered hoodie (6 months)
Pink/white stripe top (6 months)
Chambray one piece (9 months)
Pink/green stripe dress (9 months)

All are pre-owned in good to very good condition. She wore these each a handful of times and they were laundered each time. The pink top has a B on the label.
