Hey Kelly! Using a larger implant to avoid a lift can be sucessfull, however, you do out yourself at high risk of *double bubble* where the tissue and/or skin sags below the implant and get what looks pretty much like a double chin on your breasts. Also, if you are borderline for a lift now you WILL need a lift sometime in the near future given the weight of the big implant will sag them furtther, often you are better off to do it all in one go rather than risk DB or need a lift 2 years down the road.
Hope this helps. x
