Wrong size on shirt’s tag and description!
Size: 16"-16.5" Neck 36"-37" Sleeve, Color: Dark Blue, Size: 16"-16.5" Neck 36"-37" Sleeve, Color: Dark Blue
We have ordered Van Heusen dress shirts in size 16.5 neck and 36”-37” sleeves for years. This shirt’s sleeves are 2-3” too short! The shirt is tagged wrong. I ordered the same size brand and shirt in a different color and you can see the difference in the sleeve’s length in the photo! Annoyed I need to return the defective item.
