Excellent value for your money
Color: Navy Blue-square, Size: X-Large
Comfortable with a slight stretch to the material. Wrinkles were minimal to nearly none after a day of wear. Material is soft with a nice feel to it. Overall great quality and would definitely recommend!

The liner of the shirt can be unsightly with the neck worn open
Color: Black-polka Dots, Size: XX-Large
Be warned, if you get black, the shirt may actually be white inside. I ordered the black with white poka dots. The shirt was nice enough an would have looked okay completely buttoned to the top, however, if you wear the neck open like the model shows in the photos, the shirt is not like that. The shirt has an unsightly white liner which totally shows if you wear the neck unbuttoned at all.
