I'm 5'3, weight 110, bra size small B cup. Can I realistically achieve the look and size of Kate Upton? (Photo)

Thank you for the question. Unfortunately, online consultants will not be able to provide you with specific enough advice (regarding specific breast implant size/profile) to be truly helpful.  Generally speaking, the best online advice I can give to ladies who are considering breast augmentation surgery (regarding breast implant size/profile selection) is:
1. Concentrate on choosing your plastic surgeon carefully.  Concentrate on appropriate training, certification, and the ability of the plastic surgeon to achieve the results you are looking for. Ask to see lots of examples of his/her work.
2. Have a full discussion and communication regarding your desired goals  with your plastic surgeon. This communication will be critical in determining  breast implant size/type/profile will most likely help achieve your goals. 
In my practice, the use of photographs of “goal” pictures (and breasts that are too big or too small) is very helpful. In bra sizers can be useful communication tools also. I have found that the use of words such as  “natural and larger looking” or "DD cup" etc means different things to different people and therefore prove unhelpful.
 Also, as you know, cup size varies depending on who makes the bra; therefore, discussing desired cup  size may also be inaccurate.  The use of computer imaging may be very helpful during the communication process.
3.  Once you feel you have communicated your goals clearly,  allow your plastic surgeon to use his/her years of experience/judgment to choose the breast implant size/profile that will best meet your goals.  Again, in my practice, this decision is usually made during surgery ( after the use of temporary intraoperative sizers).
I hope this, and the attached link (dedicated to breast augmentation surgery concerns), helps. Best wishes for an outcome that you will be very pleased with.

Thanks for your question.  When my patients come in for breast augmentation, my nurse works with them as they try on the different sized implants which allows them to see what size they like best on their bodies. I help guide them to a shape or style implant - round or shaped, moderate or high profile - that works for their body type.  I suggest making a consultation with a board certified plastic surgeon to determine what will work best for you.
