Ribcage is 25 inches, bust is 32 inches. A size 26 sounds small and weird but many people measure their bra sizes incorrectly (ie many girls in a 32a should be wearing a 28c) so it wouldn't be an uncommon size if people wore bras the right size. However...a 32a doesn't need as much support as a larger cup size so they are fine in a 32 and most women with small ribcages do not have large cup sizes so it's impossible to find small band + large cup...Holy! size 26??
What is your bust/rib cage measurement?
You must be tiny!
