My breasts still have a torpedo shape 11 days post-op, do breasts ever stay up near the collarbone?

Your concerns are understandable. Your plastic surgeon, knowing the details  of your situation, will be your best resource when it comes to good assessment, advice, and/or meaningful prediction/reassurance.
Generally speaking, breast implants will "drop" into the pocket that was created during surgery. The rate of breast implant "settling" may depend on factors such as size of breast implant pocket dissected, tightness of the overlying skin/muscle layers, and size of breast implant utilized. Normally, it takes about 3-6 months (for some patients longer) to see the final result. It is very common for one side to settle faster than the other.
Similarly, it takes a few months for the breasts to "soften" in most cases.  Most of my patients tell me that their breast implants feel "part of them" somewhere between 3 to 6 months after surgery was performed.  As the breast implants "settle", the lower breast poles will round out (generally improving shape), and the nipple/areola complexes will seem to sit higher on each breast mound.
 There is definitely a physiologic and "psychological" (body image)  adaptation process that occurs, at differing rates for every patient, for patients who undergo any type of aesthetic surgery, including breast  augmentation surgery.  Understandably, patients often experience significant emotional "ups and downs" around the time of surgery.
 
In other words: time, patience, and close followup with your plastic surgeon are your best friends here. Best wishes for an outcome that you will be very pleased with longer-term.
 
 

At only 11 days post op you are very early in the healing process. Your breast shape will continue to change as the implants settle and swelling subsides It can take up to three months typically. Continue to follow up with your surgeon as directed. Regards, 

Thank you for sharing your question. After placement of implants, the appearance of the breasts will change dramatically over the next several months as the implants drop and the overlying tissue stretches to accommodate the extra volume. In your case the swelling from surgery is flattening your implants and holding them high on your chest.  Though they will not get bigger, the volume within the implant will redistribute towards the lower portion of your breast achieving a more natural appearance, and filling your bra cup more.   This typically starts to occur 6-8 weeks after surgery.  Hope this helps.
