The shirt is cut with a wide chest and shoulders, coupled with looser sleeves. The generous proportions are matched with a carefully considered body and sleeve length so the shirt maintains its oversized feeling without appearing too big. The shirt has been garment dyed for a perfectly lived-in color.
