As a former Jordan megafan I have to say she'll need more than implants to get the figure her sister had. Not that she's fat but she'll need a bit of workout to have a glamour model look.
Besides, when Jordan was at her biggest she had two of the most natural looking fake boobs I've ever seen. I mean, you could tell she was fake mainly because of the size, but they had no stretch marks, scars, strange shape or implant anomalies at all (even after quite a few surgeries!). They were also quite soft and that's something I don't think her little sister will have. Her current DD boobs look much more fake than her sister's former FFs.
