Whatever's Wrong, It Has a Page
Every fit problem is a mechanical message. Pick yours: each page explains the cause, computes the exact size to try from the one you wear, and says honestly when the answer is construction rather than size.
One wrong size, many symptoms
Most fit problems are one problem wearing costumes. The legacy +4 measuring rule handed a generation bands one size too big and cups one letter too small: a combination that simultaneously produces a riding band, slipping straps, spillage and a floating gore. That is why so many pages above end at the same answer: the snugger sister size. Start from your measurements, and most of the costumes come off at once.
Fixing fit: answered
How do I know if my bra fits correctly?
Five checks: band level and snug on the loosest hook; cups smooth with no gap or spill; gore flat on the sternum; wires on ribcage, not tissue; straps resting, not carrying. Fail any one and the pages above decode it.
Can one size change fix several symptoms at once?
Often: because most symptoms share one root. The classic wrong size (band too big, cup too small, the +4 legacy) simultaneously produces riding, slipping straps, spillage and a floating gore, and the snugger sister size clears all four.
What if I try the computed fix and it's still wrong?
Then the message wasn't size: it was shape or construction, and each page flags those cases. The breast-shape guides and the fit diagnostic on the calculator take over from there.

Start from the measured size
Two measurements, no inches added. Then every sign on this page has a one-step fix.
