36D

36D is a bra size used in Western lingerie sizing, representing a band size of approximately 36 inches and a D cup. It is commonly found in the United States, the United Kingdom, and among many international retailers. The exact cup volume associated with D can vary by brand and style.

Measurement and interpretation: The band size is the measurement around the torso just under the bust, typically rounded to the nearest even number. The bust measurement is taken around the fullest part of the breasts. The difference between bust and underbust.

Cup sizes are traditionally linked to this difference: A about 1 inch, B about 2 inches, C about 3 inches, D about 4 inches, with larger cups following (e.g., DD/E around 5 inches, DDD/F around 6 inches). Because band sizes reflect the torso measurement, a 36D can fit differently depending on brand and style. Many people try sister sizes (for example, 34C or 38B) if the fit is uncomfortable in one size.

International differences: US and UK sizing generally use the same cup letters but may differ in band fit and sizing conventions. European sizing often uses metric band numbers (for example, 80D, 85D) and can differ in cup volume, so conversion charts provided by brands are recommended.

Fit and style notes: D cups vary in appearance based on breast shape and the bra’s construction. Common bra styles for this size range include full-coverage, balconette, and t-shirt bras, with fit adjustments through the band, cups, and straps. A properly fitted 36D should have a snug band that stays in place and cups that fully encase the breasts without digging or spilling.
