I too have experience with this. I was a DDD and am finally getting down to a DD. I double bra if I know I'm going to be doing a lot of running/jumping. I wear a regular one and a sports over the top. Here's a link to a Spark article that might be more help.

Her first step is going to be to get properly fitted; Even if she's been wearing the same size for a while, our breasts can change, and a good fitting is critical. Before she orders anymore, she needs to make sure she's the right size.
You won't get any laughter from me; I hit 40F when I was nursing my first child, and it was absolutely miserable. I've since settled to a much more manageable 40D.

This isn't actually answering your question, but I thought I would share my experience. My bra size is 42DDD so I do have some experience here. I have started "double braing". I wear my regular bra and then my sports bra over top of that. That is the only way I get the support that I need.

Not sure where to ask this question but help is seriously needed. My oldest daughter has decided to join me and another daughter in our love of running. She, however, has very large breasts but is quite thin so her normal bra size is yes, 30 F. Please don't laugh, she hates her breasts and the insurance company refuses to pay for the $10,000 reduction! She ordered some sports bra's especially made for the large breasted and they don't fit. Any suggestions about where else she cab buy a good sports bra?
