The first time the Roman boy donned the toga virilis, he wore the (tunica) recta as an undergarment; for the sons of equestrians and senators, it was furnished with the insignia of rank (latus clavus). The long, white tunica with tight upper sleeves which the Roman bride donned on the eve of her wedding, which she slept in and wore on her wedding day was called recta or regilla (Plin. HN 8,194).
