This is a men's polo shirt purchased two years ago from the AOKI online store. Since it's sold by AOKI, a suit retailer, the tailoring is geared towards business wear (i.e., Cool Biz). Of course, it's also recommended for casual wear. The material is 70% cotton, but it feels light and crisp, similar to linen. The slits in the sleeves (as shown in photo 5) and the wide-opening collar buttons provide a cool and open feel. The color is light beige and the design is simple, making it easy to pair with suit pants or chinos. I've only worn it twice, so there are no noticeable stains. However, as shown by the red arrow in photo 7, there is a small, barely noticeable spot. Please be aware of this. The fabric shows no signs of deterioration, so you can still wear it for a long time. 〇 Product Description Men's Short-Sleeve Polo Shirt ・Brand: AOKI (Suit Retailer) ・Color: Light Beige ・Size (Measured Flat) ・Shoulder Width: 45cm ・Chest Width: 50cm ・Sleeve Length: 22cm ・Length: 64.5cm ・Material Cotton: 70% Nylon: 30% ・Condition: Used Worn twice, with no noticeable fabric deterioration or stains.
