I have one between my breasts and whilst it didn't stretch as such it did kind of distort a little when my breasts were at their largest. The thing I'm more annoyed about than stretching is the fact that it's gone blurry. I've had it for nearly 20 years now and I guess i should have expected it but all the detail has gone. It's just a celtic crucifix but it had a lots of filigree type lace work in the middle of the cross... originally... now it's just a blue blur. I guess it will keep getting worse as i get older and eventually just look like a plain blue cross. If I had known about the blurring i may have had a simpler design done instead.
