Could you tell if a woman's breasts were real or enhanced, though? Sometimes it depends on the boob job. If she had a lot of breast tissue to begin with, or if she got her implants under the muscle rather than over, if she naturally has a lot of subcutaneous fat, the size and shape of the implant, how many years since her surgery, silicone vs saline, the skill of the surgeon, the amount of scar tissue... there are many different factors. In other words, not all boob jobs are created equally.
Having seen many, many enhanced breasts over my lifetime, I would argue that an exceptional boob job can be difficult to detect from natural. Just my two cents.
There was a rumor at one point that my breasts were enhanced. They most certainly are not, but again... is it so obvious? As I'm naturally curvy, it would be hard to tell.
