Super soft, runs small, but to be fair I was advised of this when purchasing. Nice quality and a good crew neck line. Definitely will order more. A bit disappointed with the colour of the dots, they are more of a light purple than the advertised rose gold.

Like everything about the T-shirt! I feel like it might be a mm off center but hard to tell. Really happy with the product
