This "Witch's Rugby one-piece" incorporates various details from a rugby uniform, a rugby shirt. First, a rugby shirt is known for its white collar. It looks great even when worn with the buttons open, showing the white part of the placket. The body is not made of jersey fabric, but rather a sturdy twill fabric with clearly visible ridges. The cuffs are ribbed, just like a rugby shirt. It's simple, but the contrast between black and white makes it a moderately sporty yet sophisticated witch dress.
