Thanks for your question. Given your height, weight and current size, a 485CC implant would put you at >D cup. Whether this is DD or beyond is hard to say. There is a loose rule that it takes about 200CC to change to the next cup size. This is not a hard and fast rule, but a generalization. A 485 CC implant that is the Moderate Plus with Mentor or Moderate profile with Sientra will be 13.5-14cm wide. I would be surprised if your base diameter was that wide. The risk of using that large an implant is that it increases the possibility of implant malposition as well as capsular contracture. A larger implant will weigh more as well. Not everyone has the same measurements however and that is why it is important to meet with someone who can explain these variables. Find a Board Certified Plastic Surgeon who is an ASAPS member. Best of Luck!
It is hard to determine whatcup size you will be after surgery. You will have to wait one month aftersurgery to go bra shopping and learn your new size, remember you are going to be a little bit swollen the first weeks, so it's impossible to know what size you're going to be. You'll just have to wait and see for yourself.
