Pink silk set from China

My aunt travel extensively for her job and brought this outfit home from China for my daughter. I don't know the actual fabric but it has a silky feel. I'm trying to remember my daughter's age when she wore this and all I can say is around age 4-7. The top has stunning rose clasps with a bit of a gap so she wore a tank/undershirt on underneath. Pants have a 15" waist and a 27.5" length. There is no elastic in this waist so I used a clip to keep her pants up when she wore it. There is no damage to the material. She wore this outfit less than 8 times and for short periods so there are no rips, stains, or damage. This is a fun and extremely cute set that I'm excited to share with another family.
