Not worth the price.
Color: 2 Pack(black+white), Size: XX-Large
At best these T-Shirt should be in a 4 pack at maybe $10. Quality is not good, they are very thin, very stretchy and the collar does not hold its shape. Would not buy again.

True to size and value for your money.
Size: 8.5, Color: Cognac
Got these for my husi. He was very pleased with the look and feel of it. Danced all night at his sister’s wedding. These bad boys were perfect with his sage coloured suit! He is an 8 1/2 and we got his exact size Fit perfectly with no complaints. Material is really strong too and the price was the best overall.
