Hopefully it's animation or something else 'normal'. It's definitely weird, especially alongside the loss of sensation where my nipple was (along with phantom twinges in my non-existent nipple). I'm happy with my choice. It's nice to not worry about prosthesis and so on, which I know coming into summer swimming with the kid's I'll really appreciate. But it is all very odd having a fake boob.
All the best for the reduction - I guess if anything has gone astray with your implant they can fix it at the same time. My PS said a small lift and a bit of lipo would even me up, and I do look at my wonky boobs and consider it. But I've just gotten to the stage of healing that I can bear a 'normal' soft cup bra and have found one that does the job of making me look as even as I ever was with clothes on. Otherwise I just wear lots of patterns (yay for florals being in fashion!).
