Just when you thought bra fitting couldn't get any more complicated, it turns out that a 30 often isn't the same as a 30. It's commonly known that people with larger cup sizes tend to choose smaller bands over those with smaller cup sizes. But is this an organic decision or influenced by changing band lengths with cup sizes? I collected Bratabase data on the stretched and unstretched band lengths in a couple of band sizes of Cleo bras - the ones with the most data. The results were pretty interesting! The title is self-explanatory - this chart details Cleo's stretched band lengths. As you can see, from D-G the bands are fairly consistent. The 28s stretch to just a little over 28", the 30s stretch to a little over 30", and the 32s hover around a little over 32". All seems to be pretty normal. But then we reach the GG. The G to GG jump is known to be a place where lots of brands change scaling, cup construction and other aspects of a bra. The stretched ban...
