VPL, short for "visible panty line," is a fashion faux pas that occurs when the outline of underwear is visible through clothing. To avoid an embarrassing VPL situation, synonyms such as "no show underwear," "seamless panties," "invisible underwear," "smooth fit panties," and "thong" can be used. These types of undergarments are designed to eliminate the appearance of panty lines and provide a smooth, seamless look under clothing. With the help of these synonyms and the proper undergarments, fashion-conscious individuals can confidently wear any outfit without worrying about VPLs.
