SHEIN Baby Romper Set of 2 Size: 3-6M - Colors: Mint Green, Gray - Design: Buttoned, Long Sleeve, Romper - Material: Sweatshirt fabric, Fleece lined Washed once after purchase. Only the black one was worn once, but these two are unused. Although the size is listed as 3-6M, my 4-month-old son, who weighs 7kg and is a bit chubby, has already outgrown them. I think the sizing is generally a bit small, so please use this as a reference for the fit. These are plain, round-neck long-sleeved bodysuits with a simple design. They are fleece-lined, making them perfect for autumn and winter. They can be worn in various situations, such as everyday wear, indoor wear, and outdoor play. Please only purchase if you understand that these are used items and have been stored at home. Thank you for looking!
