I’m 5,4 145 pounds Do I have enough fat for a bigger booty and to fill my hip dips? (Photos)

Based on the photos, it looks like you're a great candidate for a BBL.  I don't recommend gaining more weight if you're comfortable at 145 lbs.  The liposuction will help enhance the shape of the buttocks and the fat transfer will fill in the hip dips and provide an augmentation.  I recommend seeing a plastic surgeon for a consultation.

Dear Danielle76808,
based on your photos, you look like a great candidate for a BBL. Liposuction of your abdomen, back and flanks should give you more curves and hourglass shape and fat transfer to buttocks should give you more projection. I would suggest you to consult a board-certified plastic surgeon because only after a thorough examination you will get more information and recommendations.
