Bad stitching
Size: Large, Color: Bright White
The shoulder seam missing stitching. So there was an inch hole in the seam. I stitched it myself but really should have returned for a replacement. I bought two others in different colors and the stitching was fine. I do love the fit of these t-shirts.

Quality clothing brand.
Size: X-Large, Color: Royal Blue
Well made and soft and comfortable. True to size. The material is stretchy and not tight fitting. I don't like tight fitting shirts. Nautica is a premium brand. Great with jeans and even better with shorts during the summer.

Nautical is a great brand
Size: XX-Large, Color: Red
Total quality T-shirt....Rich red color as shown on line - BUT was a little surprised to feel it has some nylon is the material and not the 100% cotton I thought I was buying. Up side, means it won't shrink much washing, but in the super HOT Texas heat - this year - kind of wanted the totally light feel. Love and prefer the V-Neck. Would definitely recommend this item and seller. Pkg arrived early.
