24-Inch Underbust Bra Size
A snug 24″ underbust (61 cm) is a 28 band. Slide to your bust measurement and the size appears; the table shows every cup a 28 band can carry.
My underbust is 24″: what's my size?
The band comes from the underbust alone. 24″ → 28 band whatever your bust; the bust only decides the cup letter: one letter per inch above 28.
Where 24″ lands
A 28 band in every system
Odd number? No. 24 is the 28 band directly. Bands are always even; the underbust reading between them goes to the sister size that fits.
Getting the underbust right
Firm against the ribs, level all the way round, on a normal exhale. A slack tape adds an inch and a band size.
Nearest whole inch, odd rounds up to even. Never add four inches: that is the outdated rule.
The band should fasten on the loosest hook and feel firm; move inward as it stretches over months.
