Still hot
I think a lot of guys, probably 99.9% of guys couldn't take the attention if their GF/wife looked and dressed like Allegra, and I may be exaggerating by saying one in a thousand wouldn't mind; it may be considerably less than one. Rather than accept how hot and sexy your GF is and feel proud, they feel embarrassed, not only because of all the attention, the heads turning and whispering, but because everyone they know has told the that her boobs are just too huge, that there is something wrong with a girl who wants fake boobs that size. Why would you want a GF who has boobs so big that she can't work and has trouble doing many common household tasks?
I see it entirely different. If absolutely huge boobs make the girl feel better about herself and gives her confidence, she should make them absolutely huge. If her boobs draw attention as you walk together, take pride in the fact. If your friends tell you her boobs are too big, find better friends. If her boobs get too big for doing simple tasks, like tying her shoes, you should happily help her out; it is a small price for such an amazing GF. If you have any hesitancy accepting such a girl, you should keep on walking because you don't deserve her.
