The size is indicated as 38. I've listed it as a Medium for now, but please refer to the measurement chart in the photos to make your own judgment. The color is not blue, but a greenish hue. 【Instant Purchase OK】【Ships within 24 hours】 ● About Size I try to include photos of brand tags and size labels whenever possible. I've uploaded a size chart with measurements, so please check it. ※ All sizes are approximate measurements taken with the garment laid flat. Due to the nature of clothing, there may be slight variations in measurements depending on how they are taken, so please use them as a reference only. ● About Color I take photos with my smartphone, so the colors may not be accurately captured. If you're unsure about the color, please ask in the comments. ● About Fit and Appearance I'm selling a variety of clothing in different sizes, and I can't judge the fit of most of them. I can't provide subjective opinions, so I won't be answering questions about fit. Please use the measurements and photos to make your own assessment. ● About Condition I try to photograph any noticeable issues, but I can't capture everything. There may be other imperfections such as stains, dirt, fraying, or pilling that I haven't photographed. Even if an item is unused, there may be some minor damage. Please refrain from purchasing if you are particularly sensitive to these issues. ● About Shipping I aim to ship items as quickly as possible (usually within the same day or the next day). Items will be folded for shipping, which may result in creases. Bulky items may be vacuum-sealed to compress them. I generally use either "Rakuraku Mercari Bin" or "Yu-Yu Mercari Bin" for shipping. I may change the shipping method to the most appropriate one at the time of packaging, so please be aware of this.
