Rhinoplasty to have Margot Robbie's nose?

Interestingly enough, I had a patient of mine a few months ago ask for the exact same thing! To be honest with you, without seeing the rest of your nose and face, it is difficult to assess how achievable and realistic your expectations are.  You have very poorly defined tip cartilages and nostril asymmetry.  I'd be interested to see a profile picture as well as full assessment of the dorsum and bridge of your nose to get a better idea of the light shadow transition points.  You can absolutely get more definition and a drastic improvement in the appearance of your nasal tip with tip refining techniques - that being said, an in person consultation is always your best bet such that your doc can examine the skin, facial proportions, etc.  I suggest you go on as many consultations as needed until you feel comfortable with the doctor.  Best of luck! I hope some of this helps.

I am not sure if Margot Robbie would be willing to sell her nose for any amount of money. Maybe try and figure out exactly what you don't like about your own nose, and then ask a good surgeon which parts can be changed, and which bits can't. Rhinoplasty is about improving what you've already got, not waving a magic wand. Good luck.
