36C

36C is a bra size used in many lingerie sizing systems to describe the combination of a band size and a cup size. The band size is 36 inches around the torso directly under the bust, and the cup size is C, indicating a certain relative volume of the bust compared to the band. In common sizing charts, a C cup corresponds to a bust-to-under-bust difference of about three inches, though exact volumes can vary by brand and style.

Measuring for a 36C involves two steps. First, wrap a soft measuring tape snugly around the ribcage under the bust to determine the band size. Second, measure across the fullest part of the bust to estimate cup size. Subtract the under-bust measurement from the bust measurement; the difference guides the cup letter in many systems (roughly 1 inch = A, 2 inches = B, 3 inches = C, 4 inches = D, and so on). Note that different brands may number or label cups slightly differently, and trial fittings are often necessary.

Sister sizes provide alternative but equivalent options for volume. For 36C, typical sister sizes are 34D and 38B, which maintain similar cup volume with different band lengths. This can be useful if the band feels too tight or too loose.

Fit considerations vary by brand and style. The cup should encapsulate the breast without spilling or gaps, the band should feel snug but not constricting, and straps should support without digging in. Brands differ in sizing, so trying multiple models or brands is common to find the best 36C fit.
