Looks great and no need to iron
Color: Light Blue-square, Size: Large
The wrinkle-free dress shirts from COOFANDY are an easy addition to my wardrobe. They are affordable and look nice with colors that pop and a comfortable fit. Plus, I never have to iron!

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.
