The material of #5600 only
allows stretching to a certain degree because otherwise the material
wouldn't give enough support especially in bigger sizes.
consumer especially with smaller bra sizes don't need the support and are
used to bras with less supporting but more stretchy material.
The straps of a #5600 34C have a 0.11 inches front/shoulder part and a
0.8 inches back part. This is a regular width for straps in size 34C.
Unfortunately the consumer doesn't explain, why the difference between
the front/shoulder part and the smaller back part is odd for her.
