The term “pit to pit” refers to the measurement across a garment’s chest, taken from the seam under one armpit to the seam under the other. This dimension provides a crucial indication of a garment’s width and overall fit around the chest area. For instance, a shirt described as having a 20-inch “pit to pit” measurement will be approximately 40 inches in circumference at the chest.
This measurement is particularly vital when purchasing clothing online or without the opportunity to try it on. It allows for a more accurate assessment of fit compared to relying solely on general sizing categories (e.g., small, medium, large). Its usefulness stems from providing a concrete, objective dimension that can be compared against the wearer’s own chest circumference or the dimensions of similarly sized garments they already own. Historically, such direct measurement methods have always been critical for ensuring proper garment fit before widespread standardized sizing.
