Muscle is a cut, not a size: a muscle tank is a sleeveless top and a muscle tee a short-sleeve one, and the size label on it (XL, 2XL, 3XL) is read like any other shirt label. Of the 7 muscle styles on SanMar spec sheets, only the District DT153 (women's) goes to 3XL, fitting a bust of 48-51 inches (122-130 cm). The unisex Bella+Canvas BC3483 and Next Level NL3633 stop at 2XL.

Big and tall covers two different things, not one. Tall sizing adds body length at the same chest width. Big sizing adds chest width at standard body length. Port and Company's tall line runs LT through 4XLT, each one matching its letter-equivalent regular size in chest width and adding a consistent 3 inches of length. The regular Big line runs all the way to 6XL for chest width alone, at standard length. Tall Sizes: LT to 4XLT, Port and Company PC61T Every tall size shares the exact same chest width as its letter-equivalent regular size and adds a uniform 3...

A fitted 7 1/4 hat measures 22 3/4 inches, about 57.7 to 58 cm, around the head. A fitted 7 3/8 measures 23 1/8 inches, about 58.7 to 59 cm. Fitted hat sizes are a direct head-circumference measurement translated into a number, not a size label like small or large, and this is where the two systems actually meet. New Era and Richardson both publish an official fitted-size conversion chart, and their inches figures for every size match exactly. The centimeter figures differ slightly only because of rounding precision, New Era publishes one decimal place, Richardson rounds to the nearest...

XLT and XL share the exact same chest width. The T only changes body length: on Port and Company's tall line, XLT measures 24 inches across the chest, identical to regular XL, but adds 3 inches of extra body length (34 inches versus 31 inches) for a longer torso fit. Tall sizing exists for one reason: a standard XL fits a 24 inch chest at a 31 inch body length, which is too short for a taller frame with the same chest width. The tall version keeps the chest measurement identical and only stretches the body length, so the fit...
