Does anyone think I might have capsular contracture? I’m 10 months post op 605cc silicone soft (Photo)

It's hard to fully evaluate CC based on your photos alone. Are they firm? Painful? Did they start lower and migrate up higher?
You likely could've benefited from a mastopexy - that won't improve the cleavage though - just change the nipple position that is a touch too lower.

I would argue you have you quite a bit of cleavage. You have fairly large implants and they're practically touching without a bra. You could always get a 2nd in person opinion to properly assess for CC but it's likely just residue skin laxity causing the nipple drooping.

I would recommend a lift. I would recommend finding a surgeon certified by the American Board of Plastic Surgery with experience in complex breast issues. This surgeon ideally has also completed a fellowship accredited by the Aesthetic Society.

Your right implant is definitely sitting high. Is it firm? If the breast gets firmer and the implant displaces up, that is a capsular contracture. The alternative is just an implant that is sitting high and has not dropped. It has been 10 months, so I would expect your implant to drop by now. Usually you need a bra to show a deep cleavage because breasts tend to separate without one. You are in a gray area regarding a lift. If you want your breasts lifted (such as by lifting them with the cups of your hands) and if you want your nipples situated higher, then there is really no choice. The best type of lift is a vertical lift. I use a medial pedicle. The inverted T "anchor scar" method is obsolete, in my opinion.
