Great Quality Shirt That Looks More Expensive
Color: Cream, Size: Medium
This is my 2nd COOFANDY purchase for my husbands wardrobe! Really impressed with this Knit Button Down Textured Polo Shirt. The material feels soft and breathable, and the textured design gives it a more elevated look than a basic polo. It fits well, looks great dressed up or casual, and is perfect for vacations, dinners, or summer events. Excellent quality for the price.
