The photos are limited, but you appear to have a lean frame with modest available donor fat. A BBL can sometimes soften the waist-to-hip transition and add some buttock fullness, but the result is limited by how much fat can be safely harvested and how much survives. If you want a very round, high-volume, traditionally feminine buttock, fat transfer alone may not be enough; some patients consider staged fat grafting or buttock implants, but implants have their own risks and maintenance issues.
