I prepared these for my child's kindergarten entrance ceremony and wore them a couple of times after that. All items are in good condition and can still be used. The striped shirt and pants are Ralph Lauren, the white shirt is UNIQLO, and the vest is from the brand parentsdream. The white UNIQLO shirt is size 100 and has been worn once. This is a non-iron shirt that is wrinkle-resistant. I think these can be worn in various situations, such as formal events like weddings.
