Baby size 80 long-sleeved cut-and-sew and a thin sweatshirt. I think it will be cold in the dead of winter, but it might be okay if you wear long underwear underneath. It's a thickness that seems wearable around April and October. Please also take a look at the lining, which is shown in the photos. There are some marks left on the washing tag because a name sticker was attached. Instant purchase is OK(^^♪ Please refrain from purchasing if you are concerned as it is stored at home. Thank you for looking.
