This is a three-piece set: vest, pants, and shirt. I wore it twice for weddings, etc. Both the vest and pants are made of very light and thin material, so I was very satisfied because my child could spend a long time wearing them without feeling burdened. The pants have a pumpkin pants shape when worn, which was cute. It's recommended for spring and summer, but you can also wear it in autumn and winter by wearing long sleeves or tights. No pets or smokers. I will fold it up small when shipping. *Stuffed animals and flowers are not included.
