and this one:

Roland59 has an EasyPose  tape measure in freestuff that might be helpful.

 And once you have the measurements, here's a handy bra size calculator so you can be sure that  Vicky has comfortable, well fitting support - and perhaps answer the age old question of whether the camera adds a cup size.

Roland's measuring tape is apparently only for Poser. Don't know how to make it work for DS 4 or if that's even possible.

Looks like all these are for Poser and not DAZ.  Sigh
