The patches and fixes for Breeze's body(including compatibility with Robert's Male body) are all right there on the Files tab.
The neckseam is not as pronounced (imo) for Breeze's male as it is for virtually every other
female body mod. However, it is still visible. Seems like a native Fallout 3 issue that can only really be overcome with some stylish neckwear. For that, I recommend Kikai's Equipment.
Regarding female body mods- whichever you choose, I highly recommend dimon99's experimental smaller female hands. They look fantastic, as they are truly feminine hands, not the ruddy knuckled man-mitts of the original.
