SIZE AND FIT:
Your shirt will be printed on a high-quality, soft and comfortable unisex t-shirt.
Sizes run true to size, which takes the guesswork out of ordering. If you like your t-shirts loose or oversized - size up. For a more fitted women’s style - size down.
If you are looking for the 'shirt dress' look you see in some of the photos, size up 2 or 3 sizes.
