Ribbed design on the sides under the armpits. Made in Japan, so it has a solid construction. The ribbing is also sturdy. It originally has a vintage-like processing and print. It has faded a bit, but those who like vintage designs probably won't mind. Please refrain from purchasing if you are sensitive to such details. - Brand: SMOOTHY - Size: S - Color: Khaki - Fleece lining Thank you for viewing.
