Do I have symmastia or is it tenting? (Photo)

Your breast implants are too large for your frame and are causing tenting. Some of this may settle down with time as your tissues stretch and relax.

Dear Krissy10,
I understand your concern. However, without a proper assessment, it would be difficult to determine what is wrong. It is best that you visit your plastic surgeon for further assessment or ask for a second opinion. Only after a thorough examination, you can get proper recommendations and advice.

From the provided photos it does not appear you have symmastia. The implants do appear close and are occupying much of the available pocket space, but there does seem to be separation between the pockets. Hope that helps.
