44C

44C is a bra size used in many North American and some international sizing systems. In the common US framework, the first number, 44, refers to the circumference of the torso around the underbust and represents the band size. The letter C denotes the cup volume, indicating the difference between the bust measurement and the underbust measurement is typically about 3 inches. Because cup volumes are not standardized across brands, the exact fit can vary by manufacturer and style.

Measuring for a 44C involves two figures: the underbust measurement (taken around the ribcage just beneath the breasts) and the full bust measurement (taken around the fullest part of the breasts). Subtracting the underbust from the full bust approximate difference yields the cup size category, with roughly 1 inch per letter step (A ≈ 1 inch, B ≈ 2 inches, C ≈ 3 inches, and so on). Brand differences and padding can affect the realized size, so many shoppers try several sizes or styles within a brand.

Sister sizes for a given cup volume are sizes that maintain the same cup capacity but with different band letters. For 44C, common sister sizes include 42D and 46B. If a 44C feels too tight in the band, trying a 46B or a 42D in a different style may improve the fit.

In practice, 44C is relatively common among full-figure and plus-size bras. Fit can vary by brand, cut, and foam or padding, so it is advisable to consult the brand’s size chart and try multiple styles when possible.
