Thank you for viewing. This is a thin knit that can be worn in spring, autumn, and winter. How about wearing it over a shirt or as an inner layer under a jacket? The size is M, but it fits me perfectly with my height and weight, so even those who usually wear S size can wear it. I have measured various parts, so please compare it with your own knitwear. 100% wool. Please consider this if you understand that it has been stored at home. If you have any questions, please feel free to ask. *It may be folded small when shipped. Color...Gray Neck...V-neck Material...Wool Stains, tears, odors, etc....None Color...Gray系 (Gray-ish)
