Some of these shirts arrived in perfect condition and looked flawless. ONE DID NOT!
Size: 20" Neck 37"-38" Sleeve, Color: Cameo Blue, Size: 20" Neck 37"-38" Sleeve, Color: Cameo Blue
Three of these shirts arrived in perfect condition and looked flawless. The sizing is fantastic: it matches the listed measurements and fits a curvy man’s figure perfectly. ONE SHIRT, however, did not arrive in perfect condition. It looks like they took it out of its original packaging, damaged it on purpose, and put it in a trash bag in very poor condition to ship it. Someone in management at this company should pay close attention to how the shipping and courier staff handle the company’s products, as this will have very negative consequences and generate unfavorable reviews for the company and its revenue. Look at the shirt on the far right!!

With this shirt I say I do
Color: Khaki, Size: Small, Color: Khaki, Size: Small
This shirt definitely compliments the suit my son bought. Very light ,very comfortable,not quite tight fit ,but I can say that it fits perfectly .It matches well with a few colors ,purple being one of them . For having a teenager that at times mistreats his clothes ,and just throws the clothes on the hanger really any way . Not many wrinkles was really on it and I really had to fight whatever that was in his closet just to take this out and it was hanged up . For having it for more than a month I say not bad . It is worth it. And if it was me I wouldn't have any wrinkles on it what's so ever. Very delicate and easy to move in it. My son wore it to his friend's graduation party not one wrinkle on it afterwards. Very casual look. I will buy more for him

Nice Shirt
Color: Lake Green, Size: XX-Large
Nice shirt. Fits well. Fabric is heavy but it feels durable. Almost feels like a baseball jersey. Nice casual shirt for work.
