Nice, but...
Size: 16"-16.5" Neck 32"-33" Sleeve, Color: Tulip
The shirt is nice and fits well. However, it's not slim fit. It's just regular fit and "slim fit" should be removed from the description.

Stylish shirt
Size: 14"-14.5" Neck 32"-33" Sleeve, Color: Ash Green
Perfect fit and size, as promoted. The quality and feel (comfort) are nice. The color is a little lighter than what I could see on the screen, but I liked it. The shirt is not too thin or thick.
