Fit
Relaxed, roomy unisex fit. Because it's garment-dyed for that soft, washed color, it runs about a half to a full size smaller than a standard tee. So if you're between sizes, or you want the classic oversized look, size up.

Width is measured across the chest one inch below the armhole, laid flat. Relaxed unisex fit; because it's garment-dyed for that soft, washed color, it runs about half a size to a full size small, so size up if you're between sizes or want it oversized. Measurements vary slightly from batch to batch.
