Usage

What does seamless mean? Seamless describes a garment or something similar as having no seams. A seam is a line of stitches that join two pieces of cloth, leather, or the like, such as you might see at the bottom of a pant leg. A garment without seams, such as a pair of stockings, is seamless. Figuratively, something that is seamless is smooth or continuous, such as a conversation that flows back and forth between people with no one talking over others. A transition from one school to another in which you don’t encounter any problems and immediately feel comfortable at the new school could be described as a seamless transition. Example: The transition from scene to scene was seamless.
