Formal Suit 4-Piece Set For 1-2 Year Olds - Long-sleeved shirt - Vest (Upgraded with high-quality buttons) - Pants (with pockets) - Red bow tie (Includes a loop to attach to the shirt buttons) - Color: Dark Gray - Size: 90-100cm - Material: Unknown Thank you for viewing. Worn only once for a wedding. Worn when the child was 1 year and 3 months old, with the sleeves slightly rolled up. It was winter, but the venue was warm, so the vest was taken off quickly and is almost unused. The original buttons looked cheap, so they were replaced with more expensive ones. I think it's the perfect fabric and design for the coming autumn and winter season. The material of the shirt is unknown, but it has a textured, slightly rough feel, and seems to be a fabric that will be okay even if the child sweats.
