Surprised at the quality and style for the price point
I love the shirt and love the quality and love the way it fits. For the price point, it’s a really good T-shirt. I can be a brand ambassador if you guys would like. I do like the clothes a lot. Style, value, comfort and softness all great! I actually have 3 shifts and one pants from this brand and love all of them. Contact me to be a brand ambassador.
