What would be the best procedure to fix my asymmetrical breasts?

Far more important than the technique is the skill and experience of your plastic surgeon. Choose your surgeon rather than the technique and let them explain why one technique may be better than another. See the below link on some suggestions on finding the most qualified Plastic Surgeon for a  Breast Augmentation.

HI there, Thank you for your question. You could choose to have a breast lift on the right side to correct some asymmetry. Your scar will go around the areola and down the breast, you may require a small incision in the breast fold. It is best to see a plastic surgeon and be assessed in person. Best, realdrsix

very easy to lift the breast and make the areola smaller. probably take about an hour. go get a consult.  on a personal note , doubt the guys you have been intimate with have perfect bodies either so relax

There's no reason you should be dealing with this. There's a relatively straightforward fix. A small reduction and lift of the right breast. They will never be identical, especially because one will have a scar (lollipop or short anchor pattern) but at least they will able to be very close to a match. Definitely go on a consult or even two, and come up with a gameplan with a doc you trust.

Thank you for your question and photos. Many women have similar concerns and are afraid to ask, they just suffer.  You do not need to suffer.  Answers and solutions are as close as your nearest board certified plastic surgeon.  After a consultation, they would be able to assess the options with you and you could choose the option that makes the most sense.  Based on the images you may be able to undergo a reduction of the larger areola alone.  This is a procedure that may be amenable to an office procedure under local anesthesia.  Always seek a board certified plastic surgeon.  Good luck.

Thank you for sharing your photos, and my recommendation is a right breast lift with areola reduction. You would have an incision around the areola and underneath the breast. Your size looks great and you should be happy with the results. Consult with a board certified plastic surgeon who will discuss a treatment plan that will work best for you. 

I appreciate your questions. I would suggest bilateral breast lift & bilateral breast implants of different sizes. You still have beautiful breasts and you should not let the asymmetry affect you. The scarring can be significant but you can consider Embrace scar prevention for better results.
Best wishes, Dr. Aldo

I would advise you that most women have a degree of asymmetry which tends to be more obvious in photographs. You have full natural breasts so you have a lot to be pleased with!
If you really want surgery to correct then you could have a small right breast reduction. This could make the breast smaller, lift the breast and make the areola smaller.
As a minimum you would need a scar around the edge of the areola, a vertical scar from the areola to the infra-mammary fold and probably a scar in the fold under the breast.
Scarring is always uncertain. Some people make great scars and some people's scars will stretch or become lumpy and red e.g. hypertrophic or even grow beyond the area of the wound in what is called keloid scarring. Scarring is determined more by a patients genetics than by the surgical technique.

Hello there, thank you for the photos and the questions. Yes you can have the areola reduced to match the left side. In this case i would recommend you to have a breast lift (mastopexy) on both breast, so you can have a better asymmetry.
Good Luck.

     It is possible to correct the differences between your breasts, making the right one less droopy and also making the areola smaller to match the left.  This would involve a breast lift (mastopexy)  with a scar around the areola and vertically downward from the areola (the "lollipop or tennis racket" shaped incision).  Discuss with your board certified plastic surgeon and good luck.
