I'm 10 days post and feeling great physically. However, I'm feeling as though I went too big? (Photos)

Thank you for your question and photos.
In reviewing your photos, you look great!  It is common to see patients feel they went too big right after surgery, as the breasts are swollen and bigger than they will be long term, and it takes time for patients to get accustom to their new breasts.
I would give it at least 3-4 months before you decide if they are too big, as most of the swelling should be resolved by then.  
Best wishes,

At less than two weeks postop, it's really still too early to say... even for you to say.  You're still going to be a little swollen, they're likely going to settle down a little more, and your skin and muscle are going to relax over the course of weeks to months.  
From what I can see of your body size in these couple pictures, they look to fit you well.  Best of luck with your continued healing!

Hi ,
After reviewing your pictures and detail, I think you look great. The issue of size is a complex and personal question for every patient. Most women take a bit of time to get used to their new size. Based on the picture provided I believe you have a good result. Good luck,
Dr. White

In my experience, this is not an uncommon emotion in questioning the choice of size, whether bigger or smaller. It can take many months for woman to get used to this change in her breast size. From the photograph, the size of your breast matches quite well with the rest of what we can see. Hope that's helpful.
