Yes, you certainly would be a good candidate for a breast lift. There may be some benefit in a small reduction in order to 'unweight' the breast. However, even following a breast lift, over time, there will be a tendency for the breast to droop again due to the stretched nature of your skin. However, they would not droop to the extent they are now, and a lift would certain help improve the shape. It would be still worthwhile.
I would allow a minimum of 6 months following surgery before considering any further procedures. This allows the scars to soften and settle. In the first 3 months following surgery, there is a build up of scar as it goes through a repair phase. The remodelling phase then begins whereby the scars mature. This can take more than 12 months. A waiting time of 6 months is usually a good compromise
