Debating on 300cc vs 330cc? Concerned about wide gap in sternum area (Photos)

Recently I went to a consultation with Dr. Feldman in Sugarland, Texas. He recommended I get a 330cc in order to disguise the space in between my chest....I really want to be conservative and get 300cc but am afraid I won't have a choice. Can/will I get the natural look I'm trying to achieve without having am "unnaturally" wide chest gap?If not what are my options? Also one nipples deviates slightly. I know it cannot be perfect, but any improvement is better than anything. What are my options?
