The Best Bras for 28B
Here is an honest scarcity report: of the 49 brands whose charts we track, only 2 cut a 28B. That is a fact about the market, not about your body, and it makes the short list below worth more than any hundred-item roundup. Each entry shows the brand's own label for your size and where it sits in their range.
28B in every system
Cup letters diverge above D, so the letter changes even though the bra does not. Convert by position, and match the printed tag in the table below.
The complete list: who makes 28B

Of the 2: 0 carry 28B well inside their chart, 2 at its edge. Well in range means the size sits inside the brand's chart, cut from a block graded around it. At chart edge means it is the first or last size they make, which is real but drafted at the limit of their grading. Your measured size guide: the universal 28B page.

How to choose at 28B
At 28B the challenge is rarely support, it is proportion. Standard wires and cup heights are drafted for larger frames, so on a small ribcage the wire can sit wide of the breast root and the cup top can gape even when the volume is right.
Prioritize narrow wires, shorter cup heights and stretch or partially stretch top edges. Demi and balconette cuts follow a shallower profile far better than tall full-coverage cups, and unlined stretch styles remove the rigid-cup fit problem entirely.
Band feel matters more at small sizes than reviews suggest: with less breast weight, a band that is merely adequate will not announce itself, so check the two-finger test rather than comfort alone.
Watch for: Watch for cup gaping at the top edge: it usually means the cup is too tall for your profile, not that the size is wrong. The cup gaping guide covers the diagnosis.

Sister sizes for 28B
A sister size keeps identical cup volume on a different band. If the 28B band rides up or digs in while the cup fits, the sister is the fix.
