Baby formal suit, a two-piece set. The gray and white check pattern is cute. The top is a soft cotton T-shirt material, comfortable and recommended for hot summer outings and facilities with heating. The red polka-dot bow tie is sewn on and adds an accent. The pants have an elastic waistband. This boy's suit is perfect for Shichi-Go-San, entrance ceremonies, kindergarten entrance ceremonies, birthdays, recitals, weddings, and more. The top and vest are integrated for easy on and off♪ My second and third children wore it to a relative's wedding and my older child's kindergarten entrance ceremony. Total wear count is about 4 times. Size is 80. The last time I put it on my youngest, who was 1 year and 8 months old, the top fit perfectly, and the pants were a bit long, so there was room. Please understand that this is a used item.
