My son is in a "Steve from Minecraft" phase, so I'm buying multiple turquoise shirts for the sake of being able to launder them while not taking away the clothing he loves. These are comfortable, soft, fit as expected, and the collars are not stretching out and warping despite multiple launderings. Would purchase Gildan brand again based on my experience with these shirts.

WAY too big 😞

Number of Items: 2, Color: White, Size: Small

I ordered a youth small (what my 6 year old usually wears) and it fits more like an adult small. Needed this for a costume and couldn't use since it swallowed her whole. Not worth returning because I would use about that much in gas.

Take note of the sizing

Number of Items: 2, Color: White, Size: Small, Number of Items: 2, Color: White, Size: Small

These are really great quality tshirts but the sizing was really confusing. I ordered these for my 13 year old granddaughter but I couldn’t tell if I was ordering kid sizing or adult. I took a chance and ordered these small hoping this was adult sizing and I was right. I am always happy with the quality of this brand and their cotton shirts but they need to do a better job explaining the sizing.
