Nice product but size is not as expected
Size: 3X-Large, Color: Green White
This shirt is really nice and really stands out only downside is the size isn't as expected. I usually wear a 2xl and decided to go with a 3xl and it was still a bit too fitted for me liking..Disappointed I couldnt use it

Good fit and color combos. Size L was accurate using chart. Washed cold/delicate, air fluffed in dryer turned out good.

Snazzy!
Pretty good shirt, embracing my Sopranos/ Goodfellas in the daily life. However, the red is soooo much darker than shown, otherwise it would be a 5 Star.
