Needs to be ironed
Size: 16"-16.5" Neck 32"-33" Sleeve, Color: Grey Mist
It doesn’t come with wash/dry instructions. I washed in warm water and dried on normal setting. Came out horrible with many wrinkles. Looked up instructions and it says cool wash and 10 minutes of drying. It will for sure need to be ironed. Otherwise a very nice shirt.

Great looking shirts
Size: 16.5" Neck 34"-35" Sleeve, Color: Midnight
I'm pretty picky with dress shirts and the way they fit- these knock it out of the park. Incredibly comfortable, wrinkle resistant, and at the end of the day, just looks professional and high quality. Fits true to size.

Nice shirt.
Size: 16.5" Neck 32"-33" Sleeve, Color: Grey Pearl
Quality seems good for price. Fit fine around chest and belly but tight in shoulders and arms.
