Dd1 is 14 and has got quite an ample bust, but she has really really noticable stretchmarks, particularly on her left breast.
They are very dark purple, and there is about 5 right near the top.
I was also busty at her age but never had anything like this. I have got strectchmarks on my bust but only little white/silvery ones.
They are starting to bother her, but i don't see what I can do.
