Although Adriana Lima seems to have a very large bra size, her breast implants only increased her size a 34 B cup. The plastic surgery was actually done quite conservatively - which gave her a "somewhat" more natural look. She scrunches those melons together which make her appear to be more busty. Before plastic surgery, Adriana Lima's breast size was just an A cup. She took the smart approach by not increasing her breast size by more than a cup.
