"Bib-and-tucker" refers to one's best or fanciest clothing. Itβs the outfit youβd wear to a special occasion, like a fancy dinner or a graduation ceremony. Think of it as your Sunday best, the clothes you wouldn't want to get dirty. It implies a level of formality and care in dressing. It's less common in everyday speech now, but the phrase evokes a sense of dressing up for something important.
