Which type of clothing typically has noticeable flaws, such as holes?

The correct choice reflects a category of clothing known as "seconds." This term is specifically used to describe items that possess noticeable imperfections, such as holes, misaligned patterns, or other flaws that prevent them from meeting first-quality standards. The production process may have resulted in these items having defects, making them less desirable for retail sale at full price.

Irregulars, while they may also contain flaws, often refer to items that are flawed in a less noticeable or formal way, usually due to minor discrepancies from standard specifications without significant impact on functionality. Markdowns refer to items that have been reduced in price, commonly due to slower sales or seasonal clearance but do not inherently imply defects. Vintage clothes, while they may show signs of wear or age, are collectible items and their value is often enhanced by their historical importance, rather than diminished by flaws. Thus, the term "seconds" is the most accurate in describing clothing with significant flaws.
