I'm a slim male that wants a feminine looking bum, hips and waist

Yes, you can absolutely achieve improvement in feminization of your body with BBL and it is specifically the lipo body contouring that shapes a BBL and gives you curves. Find a board certified plastic surgeon who specializes in BBLs to get the best results. Good luck.

Hello dear, thanks for your question and provided information as well.... I suggest you to upload pictures next time so I can help you better with what you're describing me.. I recommend you to get an evaluation with a board certified plastic surgeon to get the procedures you're looking for, and if you have much fat, you will get really good brazilian butt lift results, good luck!

In order to answer your question, a  picture of your abdomen and back would help. Since you have lost a significant amount of weight, I'm concerned that you may need a combination of skin excision (for the skin laxity) and fat grafting. However, in my experience, massive weight loss patients often do not have a lot of donor sites for fat, and will require buttock implants to achieve the appropriate projection.
