I dressed my child in this for a commemorative photo shoot when they turned one year old. It has only been worn once and is in excellent condition. The size is listed as 100, but when I put it on my child, it felt like it was between 80-90, so I'm listing it as size 80. It's white, so I think an inner layer or petticoat is necessary to prevent see-through. It's a very cute dress with lots of lace♪
