Hi Happy Girl.
Pleased to hear you're out of the op in good condition. You've done well for 400cc. In my opinion, it might be a bit early to see how your breasts are going to finally settle. Never being through this part of the journey I'm not totally clued up on the mechanics of the procedure.
Whether or not the correct type of bra may be able to 'redirect' the 'girls' into a more favourble position may be an area to solicit some advice. But surely 400cc should be adequate volume to create the cleverage you want.
As for the skin, do you regularly use a skin moisturiser? If you have problem skin, maybe a few applications every day may give the skin more elasticity.
Let us know of any developments
Be safe, well and happy
Lotsa huggs
Catherine
