Thank you for viewing. This is a set of 5 dress shirts. The colors are white, light blue, dark gray, black, and wine red. Made of 100% cotton, the fabric has a structure that traps air, absorbs sweat and releases it, allows heat and moisture to escape, and is highly breathable. This characteristic provides a comfortable wearing experience regardless of the season. All sizes are neck size 43cm. Please see the 7th photo for details. I think these can be used in various situations, such as business or events. Please comment if you would like to purchase individual shirts. Please consider this opportunity.
