Check Your Fit
Bra Fit Checker
A calculated size is a starting point. This checks how a specific bra is actually fitting you right now.

Why check a specific bra, not just the size
A calculator estimates a starting size from measurements alone - it cannot see cup depth, wire width, fabric stretch or how a particular construction sits on your body. This tool looks at the actual bra instead, and points to the most likely cause rather than assuming the size is wrong.
What this checks
-
Band
Whether it stays level and holds most of the support on its own.
-
Cups
Whether they contain the tissue without gaping, cutting in or wrinkling.
-
Centre panel
Whether it sits close to the chest, and when that's not a reliable signal.
-
Wires
Whether they follow the root of the breast without pressing on tissue.
-
Straps
Whether they stabilise the cups without carrying all the support themselves.
-
Stability and condition
Whether the fit holds up once you move, and whether the garment itself has stretched or distorted.
How it works
Answer what you notice about the band first, then the cups, wires and straps. You can skip anything you're not sure about. The checker weighs your answers by how likely each one is to explain a fit problem, then returns the most probable explanation with a specific next test to confirm it, not a single guess treated as certain.
This is a fit check, not a medical assessment. Persistent pain, a new lump, skin injury or a sudden one-sided change should be looked at by a healthcare professional rather than treated as a bra-fit issue.
