They have to be apportionate to the person. Some can carry larger breast and they still look very nice. I don't have a size in mind that is to big.
It's not about too big, it's about proportion - if the proportion is off it's just not attractive. Whether tits are too big on small girls or too small on big girls. Just my $.02

Boobs that make someone look so top heavy, that they could cause spinal problems or look far too large in proportion to the body. A small petite body with big boobs doesn't do anything for me at all sexually. They look too over sized - but thats not the persons fault just what they were given - either a benefit in some ways & not in others.
